Hi, as I have been working on fixing few niggles with Qt WebEngine on Flatpak, I suspect the same issues will be encountered when making SFOS Qt update. As far as I know, Qt WebEngine is not supported on Android, so we are on our own with libhybris devices.
Issue has been summarized together with the current workaround at https://bugreports.qt.io/browse/QTBUG-82423 . In short, - with hardware acceleration, you jittering of the web page while you scroll or play video - all Snapdragon workarounds from Chromium source are not applied as they all check for "os=android". When I tried to apply workarounds manually via QTWEBENGINE_CHROMIUM_FLAGS variable, they didn't help. What worked was QTWEBENGINE_DISABLE_GPU_THREAD=1 QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu-compositing --num-raster-threads=1 --enable-viewport --main-frame-resizes-are-orientation-changes --disable-composited-antialiasing" That way I lost GPU composing, but got other parts of HW accelerated rendering, WebGL sites working. Hopefully, this info will help. Cheers, Rinigus
