Some of the flickering can be gotten rid of by disabling hardware-acceleration for qtwebengine.
I’ve got
`export QTWEBENGINE_DISABLE_GPU_THREAD=1
export QTWEBENGINE_CHROMIUM_FLAGS=“–disable-gpu-compositing --num-raster-threads=1 --enable-viewport --main-frame-resizes-are-orientation-changes --disable-composited-antialiasing”`
in .bashrc.
Note that there is still enough flickering left to annoy, and some (appimage?) apps dont seem to register the setting.
It’s German, and you’re about as right as anyone trying to say a German word in English can expect to get.
