Created attachment 118544 [details] Screenshot illustrating the bug STEPS TO REPRODUCE 1. Choose a window which minimum allowed size is more than 1/2 width and 1/2 height of the screen (e.g. systemsettings5) 2. Move it to the corner to stretch it to 25% of the screen (best reproducible when moving to the top left corner) 3. Resize it very slightly OBSERVED RESULT The window contents are not fully rendered (see the screenshot) EXPECTED RESULT The window contents are fully rendered SOFTWARE/OS VERSIONS KDE Plasma Version: 5.14.5 (also reproducible on 5.15.2) KDE Frameworks Version: 5.54.0 Qt Version: 5.11.3 ADDITIONAL INFORMATION
And this happens reliably with other windows too? Please include output of: qdbus org.kde.KWin /KWin supportInformation
(In reply to David Edmundson from comment #1) > And this happens reliably with other windows too? Could reproduce it with Kile and System Settings (other windows have a smaller minimum size). Other people in KDE Russian Telegram channel could reproduce it with other applications, like Octopi. > Please include output of: > qdbus org.kde.KWin /KWin supportInformation https://paste.ubuntu.com/p/CHMzSwXYCR/
Information was provided with comment #2; changing status for inspection.
