Committed on 08/09/2026 at 13:00. Pushed by filipf into branch 'master'. Fix choppy cached pixmap/icon rendering under fractional Wayland scaling If we fire up almost any QtQuick app with Oxygen while using fractional scaling, we'll soon spot rendering glitches and choppiness. The glitches can be observed with: radio buttons, slider handles, and icons inside buttons. These issues are related to pixmaps. Oxygen tends to cache them for rendering UI elements, but it never saved the DPR. Also, the DPR support introduced so far only checked qApp->devicePixelRatio() and not the actual painting surface. With QWidgets that worked fine, but qqc2-desktop-style exposed DPR mismatches with QtQuick. To fix this, this patch makes several changes: - first it adds a new helper function that helps grab the right DPR - then it makes the affeceted control pixmap generators cache DPR - and ports icons pixmaps on Qt6 to not look choppy when rendered inside UI elements - as bonus, it also fixes the annoying little line between the titlebar and the window background The end result are finally proper visuals outside of QWidgets apps.
