Probably unrelated but i also noticed fractional scaling is the source of another bug where kwin's window decorations have empty pixels with klassy: https://github.com/paulmcauley/klassy/issues/149 Still happening with 24.08.1-1 and qt 6.8.0 Git commit 94304ed698014d1ea519954433581d5ab5de00c3 by Christoph Cullmann, on behalf of Luca Carlon. Committed on 28/05/2025 at 05:36. Pushed by cullmann into branch 'master'. Fix for glitches in highgpi displays A fix for glitches in highdpi displays was already applied in the past in #1f0cefa. It was only applied to Qt5. Apparently, with Qt6 the behavior is identical, so applying it again is necessary.

I'm still getting it in the same way with konsole 25.04.3 frameworks 6.15.0 and qt 6.9.1. Or am i doing something wrong? The fix is said to be in 25.08, so it makes sense that you still see the issue on 25.04.3 (In reply to Ilya Bizyaev from comment #5) > The fix is said to be in 25.08, so it makes sense that you still see the > issue on 25.04.3 Just updated to 25.08 and don't see it anymore.

Created attachment 172498 [details] screenshot SUMMARY konsole leaves small text artifacts when scaling is set to 125% on a 1080p monitor. The artifacts look like small 1 character wide underlines. If you refresh the window in some way like using the reset command, resize or move the window they disappear. This doesn't happen with 100% scaling and does not happen in other terminal emulators like Alacritty. I also tried running konsole with prime-run but it displayed the same symptoms. STEPS TO REPRODUCE 1. set display to 125% scaling and 1080p resolution 2. cd to a longer path like /etc/NetworkManager 3. cd back to home 4. press enter a few times OBSERVED RESULT small artifacts appear in empty spaces where text used to be EXPECTED RESULT konsole window is clean Operating System: Arch Linux KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 mesa 24.1.5-1 Kernel Version: 6.10.3-arch1-2 (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon 660M
