KWin support information (DP only, HDMI detached)
If both outputs have the scale scale factor, can you reproduce this issue? This sounds like the issue where desktop context menu is partially drawn because Qt handles poorly outputs with different scale factors. (In reply to Vlad Zahorodnii from comment #6) > If both outputs have the scale scale factor, can you reproduce this issue? If they have the same scale factor, like 100%, I cannot reproduce it. This is a Qt bug. (In reply to Vlad Zahorodnii from comment #8) > This is a Qt bug. Do you have the corresponding bug report ID by chance to follow the issue? |
Created attachment 145884 [details] KWin support information (DP + HDMI attached) SUMMARY Left: 4k@200% DP monitor (primary) Right: FullHD@100% HDMI monitor with Konsole, Systemsettings and Dolphin window STEPS TO REPRODUCE 1. Unplug the HDMI cable OBSERVED RESULT All windows from the right monitor move to the left and in the same stacking order as expected: Top to bottom: Systemsettings, Dolphin, Konsole However: * Konsole and Dolphin first appeared blurry and the SystemSettings very pixelated. * When hovering the mouse over Dolphin's window, it started to show black bars, then white bars, but it became clear again. * When hovering the mouse over the Konsole's window, it started showing the background image, and later while still hovering, part of its controls again.
