SUMMARY Duplicating a large image to the clipboard causes PlasmaShell to hang until it's duplicated. STEPS TO REPRODUCE 1. ```sh firefox 'https://addons.mozilla.org/firefox/downloads/file/3617883/nimbus_screenshot-15.6.9.xpi' ``` 2. Screenshot the entire page of https://ux.stackexchange.com/questions/40627/what-do-you-call-websites-that-make-heavy-use-of-vertical-scrolling?noredirect=1&lq=1. 3. Duplicate it to the clipboard. OBSERVED RESULT PlasmaShell hangs. Luckily, the `noborderrule=2` KWin rule allows me to see the window decorations at least. Otherwise, I would have thought that it had crashed. It appears instead to merely not render its contents. Firefox hangs too, *if you attempt to close it*. However, that's probably worth an issue at their Bugzilla, rather than here. EXPECTED RESULT PlasmaShell shouldn't be affected by this.

I can't get this Nimbus extension to work, so I tried it using the built-in Firefox screenshot tools, which also have a "screenshot entire page" feature. Doing that and then clicking the "Copy" button causes no hangs for me. Can you reproduce the hand with Firefox's built-in screenshot tools? Or when copying a large image in Dolphin or Gwenview?
Created attachment 172129 [details] A Screencast Demonstrating Unsuccessful Reproduction When Using Proposed Alternatives Under KWin For X11 (In reply to Nate Graham from comment #2) Are you definitely using X? I ask because it's not a problem for me under Wayland. To answer your question, it's never been a problem in Gwenview or Dolphin. However, it has been a consistent problem using that extension since I started using it last year, on openSUSE Tumbleweed, so it's not a recent regression, especially not a problem caused specifically by Fedora 40 KDE Spin's *non-default* X package. Gosh knows how nor why it affects PlasmaShell of all things.
(In reply to Nate Graham from comment #2) Regarding you not being able to get that extension to work, I'm using https://kojipkgs.fedoraproject.org//packages/firefox/128.0/2.fc40/x86_64/firefox-128.0-2.fc40.x86_64.rpm (from https://koji.fedoraproject.org/koji/rpminfo?rpmID=39142926) so maybe try it on that, if you're not already.
Note that it does temporarily hang Firefox even under Wayland (albeit not PlasmShell) so my guess is that there's a bug in Firefox that is somehow interacting with PlasmaShell under X11 that the Wayland implementation prevents. Of course, I'll try to report this to Mozilla, but PlasmaShell shouldn't be vulnerable to whatever FF is accidentally doing, I expect.
Why do you keep adding periods to the titles of your bug reports? I removed the period here on purpose, and you just re-added it. Please stop re-adding it, and please also do not argue with me over this or explain why you want to add periods to the titles of your bug reports, because it doesn't matter: here on bugs.kde.org we don't use periods to end the titles of our bugzilla tickets (in addition to the general convention in English that titles don't end in periods), so please respect that convention.
(In reply to Nate Graham from comment #6) > I removed the period here on purpose I wasn't aware you'd removed ever previously removed it - this Bugzilla instance isn't like Mozilla's or RedHat's, so I can't see each title modification in the bug timeline. > Why do you keep adding periods to the titles of your bug reports? The reason I added one was because I'm the reporter of this issue, and was looking in my bug list for another issue, where I noticed that - unlike all other issues I've filed - I had failed to punctuate this and one other correctly, so I fixed their titles to render them consistent with the others. Because it seems like I'll need to be explicit about this, that doesn't imply that I'm going to continue. I didn't realise that it was even noteworthy, and am quite happy to not care. I'll even remove them when I can, if that's of use. > here on bugs.kde.org we don't use periods to end the titles of our bugzilla tickets I've never seen such a convention documented, so it might be worth putting some text in the bug report form which mentions this. What do you propose I do for the rest of the bugs at https://bugs.kde.org/buglist.cgi?bug_status=UNCONFIRMED&bug_status=CONFIRMED&bug_status=NEEDSINFO&bug_status=ASSIGNED&bug_status=REOPENED&email1=4wy78uwh%40rokejulianlockhart.addy.io&emailassigned_to1=1&emailreporter1=1&emailtype1=exact&field0-0-0=bug_status&field0-0-1=reporter&list_id=2806205&type0-0-0=notequals&type0-0-1=equals&value0-0-0=UNCONFIRMED&value0-0-1=4wy78uwh%40rokejulianlockhart.addy.io - I imagine that removing the periods in those which aren't suffixed by other punctuation (which I expect is permitted, like question marks) would cause a rather significant amount of mail, and I don't really want to have to spend my time removing them all. You're strangely accusatory again. I've bothered to file a bug to be altruistic, and although I don't expect deference because of that, I'll be surprised if, in retrospect, you don't agree that perhaps it might have been pleasant for both of us if you had been a little more courteous. I'm evidently not going to argue about some damn punctuation.
(In reply to Roke Julian Lockhart Beedell from comment #7) Please mark that response of mine and your comment off-topic, if possible. That won't be useful for others to see.
Sorry, I was feeling frustrated and should not have expressed it publicly like that. I'll try to do better in the future. Just stop adding periods to end ends of new bug reports you open, and don't add them to old ones you touch. And more generally, just try to follow existing patterns. If no or almost no other bug reports seem to have titles that end with periods, follow that pattern for the ones that you open.
(In reply to Nate Graham from comment #9) Understood. I merely didn't notice the convention. Anyway, no worries - I'm sure there shall be a point in the future where I apologize to you for the same. Many thanks.
I appreciate it!
Adding the x11-only keyword
(In reply to TraceyC from comment #12) > Adding the `x11-only` keyword. Reproduction ------------ It doesn't apply to *solely* (Kwin +) XOrg 11, for it reproduces with `kwin-wayland-6.3.1-1.fc41.x86_64` and `firefox-135.0.1-1.fc41.x86_64`: there is a momentary hang when using the "Copy to clipboard" button. As an example, try: 1. Visit "[`worlds-highest-website.com`][1]": ~~~sh #!/usr/bin/env sh firefox 'https://worlds-highest-website.com/' ~~~ 2. Enlarge the window to approximately 5 x your display's physical size. 3. Invoke the context menu (≣⃣). 4. Select "Nimbus Screenshot". 5. Select "Visible part of page". 6. Select "Done". 7. Select "Copy to Clipboard". I've uploaded a poor demonstration at [`youtu.be/pGJnOYbtlW8`][2]. When my mouse hovers over an element is when I've clicked it, so the lag between click and execution is ≈ 1.2s. Perhaps having the KWin Debug window open would be helpful, next time?

(In reply to Roke Julian Lockhart Beedell from comment #13) If of use, I've published a trace at [`share.firefox.dev/4h3dnKk`][1]. Would a flamegraph on `plasmashell` (simultaneously) be of use? [1]: https://share.firefox.dev/4h3dnKk
Can I ask if you're still able to reproduce the issue with Plasma 6.3.5 or later?

that's how one is meant to. I've managed to compress it to 4.3 MiB, but that's too high for this BZ instance, so it's available at https://collaborate.kde.org/s/XJQYPDBXj9xWH5J.
(In reply to Roke Julian Lockhart Beedell from comment #16) Forgot to provide Plasma-specific environment information: > Operating System: Fedora Linux 42 > KDE Plasma Version: 6.3.5 > KDE Frameworks Version: 6.14.0 > Qt Version: 6.9.0 > Kernel Version: 6.14.6-300.fc42.x86_64 (64-bit) > Graphics Platform: Wayland > Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor > Memory: 30.4 GiB of RAM
Can you still reproduce this in Plasma 6.4.4 or later?
Created attachment 184080 [details] A Screencast That Demonstrates Reproduction Under KWin Wayland On Plasma 6.4.4 (In reply to Nate Graham from comment #18) Yes, with https://addons.mozilla.org/firefox/downloads/file/3617883/nimbus_screenshot-15.6.9.xpi and https://koji.fedoraproject.org/koji/rpminfo?rpmID=43883361, on: > ~~~ > Operating System: Fedora Linux 42 > KDE Plasma Version: 6.4.4 > KDE Frameworks Version: 6.17.0 > Qt Version: 6.9.1 > Kernel Version: 6.15.9-201.fc42.x86_64 (64-bit) > Graphics Platform: Wayland > Processors: 16 × AMD Ryzen 7 7840HS w/ Radeon 780M Graphics > Memory: 32 GiB of RAM (30.6 GiB usable) > Graphics Processor: AMD Radeon 780M Graphics > Manufacturer: Framework > Product Name: Laptop 16 (AMD Ryzen 7040 Series) > System Version: A7 > ~~~ I've attached a screencast which demonstrates how the duration between selecting the Application Menu's panel logomark increases from effectively 0 ms to > 1.25 s when the image is being duplicated into the clipboard. Unfortunately, this is less evident than it once was, due to my now-faster hardware. However, the third reproduction depicted is quite demonstrative.

(In reply to Bug Janitor Service from comment #20) Changing to REPORTED, because I've responded with a reproduction on Wayland in 6.4.4. Should it be CONFIRMED, though?
