Video showing the bug for systemsettings.

SUMMARY

When using Scheegan's Burn My Windows effects, opening System Settings displays a glitch where the window zooms in on the content until the animation is done as seen in the attachment. Ark undergoes something similar as the window sort of "boxes in" on the content before properly showing it, but this particular bug happens without the decoration.

The issue as been discussed at [Github] (https://github.com/Schneegans/Burn-My-Windows/issues/481) with the maintainer of the effects and he says its a kwin problem.

STEPS TO REPRODUCE
1. Open Desktop Effects in System Settings and apply any Burn-My-Windows effects.
2. Open System Settings or Ark and see the glitch as shown in the attachment.

OBSERVED RESULT

The window zooms in on the content until the animation is done when opening System Settings. In ark the window is "boxed in" as seem here.

EXPECTED RESULT

Kwin should show the content properly while animating the window.

SOFTWARE/OS VERSIONS

Operating System: Arch Linux 
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION

Apart from System settings or Ark this glitch is not seen anywhere at least as I can recall.

Comment 2 David Edmundson 2025-01-13 14:03:34 UTC

Does it happen if system settings is not restoring a maximised state?

Comment 3 Erwin Iosef 2025-01-13 14:09:28 UTC

It happens when the app opens windowed or maximized.

Well the bug is still present in Plasma 6.3 2nd Beta if it helps.

Comment 6 Erwin Iosef 2025-04-26 14:19:48 UTC

It's been a while since anyone replied but I'm happy to help with any more information or testing required, should the category be effects-various though instead of decorations?

Comment 7 Erwin Iosef 2025-05-21 16:39:20 UTC

Changed component to effects-various instead of improperly selected decorations.
NOTE: The bug is still the same in 6.3.5

Comment 8 Erwin Iosef 2025-06-18 14:31:06 UTC

Since a similar bug report was confirmed with the same problem, this bug report should be considered a duplicate of https://bugs.kde.org/show_bug.cgi?id=499101
