Description Andrey-Mattias 2025-05-10 12:14:43 UTC

SUMMARY
"Close window" buttons on each opened window in Grid-view are too small on a 4k 27' display (200% global scale in display-settings in system-settings).

STEPS TO REPRODUCE
1. Activate Grid-view KWin-Effect with shortcut (default "meta-G" in my case)
2. Observe

OBSERVED RESULT
"Close window" buttons on each opened window in Grid-view are too small for comfortable use.

EXPECTED RESULT
"Close window" buttons on each opened window in Grid-view should be about 4 times larger than they are now

SOFTWARE/OS VERSIONS
Operating System: KDE neon 6.3
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0
Kernel Version: 6.11.0-25-generic (64-bit)
Graphics Platform: X11
Processors: 28 × Intel® Xeon® CPU E5-2690 v4 @ 2.60GHz
Memory: 62.6 Gib of RAM
Graphics Processor: AMD Radeon RX 550 / 550 Series

ADDITIONAL INFORMATION
1. Can't make a screenshot because Spectacle doesn't work when Grid-view is activated.
2. "Close window" buttons on each opened window in Grid-view have reasonable size when I switch to FullHD 27' display (100% global scale in display-settings in system-settings). It seems that "Close window" buttons are just not affected by global-scale modificator.

This is an X11-specific issue; the buttons are the right size on Wayland.

Comment 2 Nate Graham 2025-08-19 20:17:55 UTC

Unfortunately this isn't feasible fixable on X11 for technical reasons. Thanks for understanding, folks!
