SUMMARY

STEPS TO REPRODUCE
1. Open Kate; open some file X in it
2.  Open a folder in Dolphin
3.  In Dolphin, double click on the same text file that you already opened in kate
4. In Dolphin, double click on some other text file that you have NOT already opened in Kate

OBSERVED RESULT

At step 3, focus is given to the window and tab in Kate where the file is already open, as  expected; at step 4, the file you clicked is opened in Kate, as expected.
BUT in both cases, the "loading" icon, a bouncing ball with Kate's symbol, keeps bouncing long after the file is open and focused. 

EXPECTED RESULT
At step 3 the bouncing icon shouldn't even show up at all, as the action to bring focus to the already-opened file is immediate. At step 4, it is expected to for the icon to show up for as long as it takes to load the file, but once the file is open in Kate and the window with the file in it is focused, the icon should immediately disappear.

I have been observing this issue for years, first in OpenSUSE and now in Manjaro.

This is not a Kate bug. The bouncing animation has a static duration.

> This is not a Kate bug

Indeed I was just realising, after filing this, that it happens with other applications too, although I had only noticed it with Kate until now. I probably very rarely open files with double click other than text files.


> The bouncing animation has a static duration.

I'm astonished. You mean it makes no attempt whatsoever to stop as soon as either failure or success to open whatever is being open is detected? I understand there being a _maximum_ duration, a timeout after which it would stop if neither success or failure is detected with certainty, to prevent the icon from bouncing around forever. But the issue is not that maximum being too long or too short, the issue is that there either is no such mechanism (stopping the animation earlier if the file loads earlier), or it's not working.


Mmmmmm wait a moment.

This does not happen, for example, if I double-click on a PDF file. It opens very quicky in Okular, and the bouncing icon stops immediately.
Same with .gz files and image files (not only with double-click but also with right-click "open with"). All these behave as expected. 
I remember seeing the issue yesterday with something other than Kate but I don't remember what it was. With most files, the duration of the animation is exactly how long it takes to load the file, and it varies, it would be hard to believe it's a coincidence.

What I'm saying is, I understand it's not Kate, but I don't understand how this can be systemsettings.

It's called Launch Feedback in system settings (Appearance -> Launch Feedback). Tbh this might still not be the place where the bug needs to be fixed, but at least the right people should see it.

Oh i see, thanks

Comment 5 Eric Armbruster 2022-09-30 14:12:16 UTC

Can reproduce with X11 only, also on git master.

Comment 6 TraceyC 2025-02-24 17:58:27 UTC

Adding the x11-only keyword
