Created attachment 180225 [details] screencast SUMMARY When using Plasma themes (including Breeze Light and Breeze Dark) other than Breeze, there is ~1 second delay between an applet fully extends and it gets focus. STEPS TO REPRODUCE 1. Systemsettings - Colors & Themes - Plasma Style 2. Select "Breeze Light". Apply. 3. Click on Kickoff. OBSERVED RESULT See attachment. After Kickoff fully pops up, it only gets the focus ~1 second later (notice the box around the Vivaldi icon changes from light blue to darker). The light blue indicator bar on the panel also appears ~1 second later. EXPECTED RESULT No delay (as when Plasma theme is Breeze).

Thanks for the screen recording, I see what's happening on your system. I'm not able to reproduce this on git-master on Solus, or on Neon Testing. In a VM with Solus on Plasma 6.3.4, I also see no difference between menu responsiveness using Breeze or Breeze Dark. The focus is slow to change, because it's a low powered VM, but both themes show the same slowness, Breeze is not any better I'll leave this open and hopefully someone else can reproduce or provide more insight
Hi! Your recording seem to have a lot of artifacts. Are you able to provide a clean one? May this be related to some graphical issue?
(In reply to Niccolò Venerandi from comment #2) > Hi! Your recording seem to have a lot of artifacts. Are you able to provide > a clean one? May this be related to some graphical issue? No, I don't see any artifacts in the recording. (If you didn't mean the mouse click effect.)

Ah, it seems like downloading and using mpv works around that; both vlc and the browser showed dialogs flickering and green overlays. Nonetheless, I can't seem to reproduce this regardless of the theme I'm using :-/ Does this still happen on a fresh user / machine?

I also noticed that both SystemMonitor and Weather applets don't have the delay. So it seems to only happen with applets taking keyboard focus.
Hi - mentioning keyboard focus got me thinking, I wonder if there's some possible connection to input methods? Do you have extra software in use to control input in multiple languages, perhaps, that might somehow be interacting with those Plasma styles?

I'm using fcitx5, but uninstalling it doesn't fix the problem. BTW, the digital clock applet, with calendar plugins enabled, also has a large delay showing those calendar events. (See attachment.) IDK if that might hint about the source of the problem.

I had an idea, looking at my settings. In System Settings -> Window Behavior -> Focus tab What do you have selected for "Window activation policy"? Can you share a screenshot of that settings page? Thanks.

As I said, I can reproduce this in a new user, so all settings are default. Screenshot attached.
Thanks for the screenshot. Using those settings, I still can't reproduce here on git-master.
I found that it's tied to the global scale factor. At 100% it's barely noticeable. At 200% there's about one-second delay. At 300% it's about two seconds.
BTW, my screen is 3200x2000.

Thanks, that's a useful detail. With Plasma 6.4.2, I do see a noticeable delay (not 3 seconds, but visible) on displays set to 3840x2400 @ 300% 3440x1440 @ 300% The good news is that I don't see this on Plasma git-master with a display at 3440x1440 @ 300% (the same LG monitor as the other test system). The fix should be available on your system when it updates to 6.5.0. This is scheduled to be released in October. https://community.kde.org/Schedules/Plasma_6 I'm marking this as fixed for now. If you can still reproduce this in 6.5.0 or later, please set this report to REOPENED. Thanks!
Unfortunately, I can still reproduce in the latest master. It's the same: the larger global scaling factor, the longer delay.
(In reply to Jin Liu from comment #18) > Unfortunately, I can still reproduce in the latest master. It's the same: > the larger global scaling factor, the longer delay. Interesting. There might be a difference related to the GPU or something else different between my system with git-master and yours. On my system, there's an integrated AMD GPU, I see your system also has an AMD. I'll set this to confirmed, since you're able to reproduce in git-master, and let the developers take it from here.
