Description David 2021-10-23 18:30:39 UTC

SUMMARY
If I get window previews over an icon from the task manager and move the mouse to the next icon (assuming there are no opened windows from the app of this icon), it will show a very oversized tooltip for that icon.

STEPS TO REPRODUCE
1. Set the icons-only task manager.
2. Configure it to show window previews on hover or on click.
3. Open multiple windows of some app, and make sure that this app's icon is placed next to a pinned icon of some app with no opened windows.
4. Hover the mouse or click over the icon with multiple windows.
5. Once the window previews are generated, move the mouse over to the next icon and watch the resulting tooltip.

OBSERVED RESULT
Displays a very oversized tooltip with the name and description of the app, which looks pixelated.

EXPECTED RESULT
Ideally, should stay with the window previews of the other app, but if it's going to display a tooltip, this tooltip should not be oversized nor pixelated.

When you are reporting visual bugs, can you please get into the habit of attaching screenshots? Often a picture tells a thousand words.

Also, you can file (for example) task manager bugs to "plasmashell | Task manager and Icons-Only Task Manager" instead of the generic KDE component in the future. That'll save me some clicks. :)

Attached is a video showing the bug. It'd BTW be helpful to have some hints in this bug tracker of when to assign a bug to e.g. the task manager vs. kwin or similar (I'd have guessed a bug like this would be more likely to fall on kwin).

Thanks. I could reproduce this in the recent past, but it should be fixed in Plasma 5.24 with all the recent changes to tooltip code. It's no longer happening to me.

If you're not sure where to put a Plasma bug, you can file it on plasmashell | general. But it's never a bad bed to file it on the applet that's experiencing the bug.
