SUMMARY *** Since 2-3 days I have issues with showing Qtwebview-based things, like Mail-content or pages in Akregator. They are sometimes simply white blank, are flickering between the content / white blank when scrolling. It has been confirmed in openSUSE and appears to be wayland-specific. *** STEPS TO REPRODUCE 1. install openSUSE Tumbleweed with Unstable repos for Frameworks and Apps 2. start into wayland session 3. try to open mails OBSERVED RESULT white blank / flickering EXPECTED RESULT works fine SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20211124 KDE Plasma Version: 5.23.80 KDE Frameworks Version: 5.89.0 Qt Version: 5.15.2 Kernel Version: 5.15.3-1-default (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-10510U CPU @ 1.80GHz Memory: 31.0 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics ADDITIONAL: https://bugzilla.opensuse.org/show_bug.cgi?id=1193036
Problem with qt opensuse package or driver no kde related and not wayland related as I don't use wayland and I have this pb.
I'm seeing this in Qutebrowser and Falkon and what fixes it is setting QT_WEBENGINE_DISABLE_WAYLAND_WORKAROUND=1 (the variablecomes from an OpenSUSE patch: https://build.opensuse.org/package/view_file/KDE:Qt:5.15/libqt5-qtwebengine/disable-gpu-when-using-nouveau-boo-1005323.diff?expand=1)
