SUMMARY STEPS TO REPRODUCE 1. Open System Settings OBSERVED RESULT After few 'scrollings', font on labels gets corrupted like this: https://imgur.com/a/fcDDgjT EXPECTED RESULT This shouldn't happen SOFTWARE/OS VERSIONS KDE Frameworks Version: 5.55 Qt Version: 5.12.1 ADDITIONAL INFORMATION Intel HD 4400 GPU, 1366x768 screen resolution, no hidpi settings
Can reproduce with touchpad scrolling. I'd thought this was fixed with https://cgit.kde.org/qqc2-desktop-style.git/commit/?id=22a2f9eaae138d6fef510800d4333b88efbb8649. it's certainly better than before, but I can still get it into a fractional pixel state with a very subtle two-finger scroll gesture.

Interesting: the initial state of the sidepanel fonts is "corrupted". When I scroll *down* to the end they suddenly are OK. When I then scroll *up* to the end, they get corrupted again. Between the endpoints they stay either corrupted or OK. HTH.
Would it be enough then to apply the patch and rebuild/install systemsettings-5.12.8 in order to see whether it works? -- QT-5.10.1 FW-5.46.0 Pl-5.12.8
OK, re-build systemsettings as described in Comment 4 but the problem was still there. So either my approach was wrong or the patch doesn't work.
The fix was made to the qqc2-desktop-style framework, so you would need to rebuild that from git master, or cherry-pick 22a2f9eaae138d6fef510800d4333b88efbb8649. But yes, that fix evidently did not completely solve the problem, which is why this bug report is still open. :)
Thanks. Was a quick trial and error anyway. ;)
Is anybody still able to reproduce this issue? I personally cannot, but I am not on the same hardware anymore. Could someone check? It's been a year since the last comment and if it's not present anymore I would like to close this.
I cannot either. Let's call it fixed for now. If someone sees it again, we can re-open.
