STEPS TO REPRODUCE 1. Use 2x scaling; 2. Open the user actions popup. OBSERVED RESULT The popup is upscaled. EXPECTED RESULT The popup looks crystal clear. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.14.80 KDE Frameworks Version: 5.53 Qt Version: 5.12
Same for almost all kwin internal windows. It's simply not implemented yet.

Add high DPI support to internal KWin windows Summary: So far we didn't try to do high DPI on kwin internal windows, such as the user context menu and tab bars and whatever. Due to wayland scaling they were the correct phyiscal size but upscaled. This patch fixes our QPA to enable Qt's high-dpi support. Note icons are still low res. This is because the global QGuiApplication::devicePixelRatio which is the max of all connected screens is static for the duration of the app. QIcon uses this when determining the DPR to use. This will require a Qt change. Test Plan: Ran at 2x on my normal DPI screen (as that's easier to see anything) * User action menu is high DPI * Window deco tooltips are still fine * Tab switcher is high DPI * Overlay in present windows Desktop grid are still ok Reviewers: #kwin Subscribers: zzag, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D18042 M +26 -0 autotests/integration/internal_window.cpp M +2 -2 autotests/integration/kwin_wayland_test.h M +1 -1 main_wayland.cpp M +12 -3 plugins/qpa/backingstore.cpp M +1 -0 plugins/qpa/backingstore.h M +22 -4 plugins/qpa/window.cpp M +4 -0 plugins/qpa/window.h M +1 -3 shell_client.cpp https://commits.kde.org/kwin/2df9d22a087f37dd48cffc53e955b8605dfeed8d
