I have pager widget inside a margin separator on a plasma panel and most of the time pager is shrunk to apply the margins as expected. However when I open my steam app (any tab) the pager widget stops applying the margin and expands. When the steam window is closed (even if just to tray) the margin reapplies as expected. This can also be seen when editing the panel as the highlighting showing the margin also disappears. STEPS TO REPRODUCE 1. Put pager widget inside margin separator 2. Open steam window visible on the desktop OBSERVED RESULT Pager will expand as though not in margin separator EXPECTED RESULT Margin continues to be applied to pager widget SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.11.1-1-MANJARO OS Type: 64-bit
does it have to be steam? maybe depends on composite being off? (as most games disable compositing) can you try to disable/enable compositing with alt+shift+f12?
What's happening here is that the margins separator app does not work to apply its margins when compositing is turned off, which happens automatically when you play a game. I can confirm this.
Margins now work again on master, even with compositing disabled, so I'll assume this has been already fixed.
