At that point it's almost certainly an issue with QQuickWidget rather than kwin. But as per plasma rules, I'll leave open till we have a Qt bug report/patch I do see blurryness/pixelation issues in QML KCMs as well. When opening the same KCMs in plasma-settings it works fine, which would support the QQuickWidget theory Can you confirm a resize "fixes" it. I put in some debug into QQuickWidget, it seems the initial backing store has a devicePixelRatio of 1 when the FBO gets made. Then it doesn't update correctly. Yes, resizing does seem to help Thanks David! *** Bug 427704 has been marked as a duplicate of this bug. *** |
Created attachment 130353 [details] Discover crisp, System Settings blurry All KDE software from git master as of this afternoon, on a system with a 4K screen, using a 250% scale factor. In System Settings, the QML-based sidebar and home screen are blurry for me with the above setup. This does not affect any KCMs, just the QML-based parts of the shell. See attached photo (not a screenshot since Spectacle can't take high DPI screenshots without losing precision, which would hide the problem in this case). This problem is not seen in QWidgets-based KDE apps, nor other QML-based apps; just System Settings.
