--- Comment #4 from Thomas Friedrichsmeier <thomas.friedrichsme...@kdemail.net> --- So, if I understand correctly, you have: Desktop PC, using system Qt, KF5 based version of RKWard: BROKEN Desktop PC, using AppImage: works Laptop, using system Qt: works Laptop, using AppImage: works Right? To me this seems to point to a problem with the Manjaro QWebEngine packages. As you diagnosed further, this seems to be related to hardware acceleration, specifically. To confirm this, you could try running RKWard with QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu" rkward Via the same environment variable, you can also set some logging options (e.g. "--enable-logging --log-level=0 --v=1"; see https://doc.qt.io/qt-6/qtwebengine-debugging.html) which might help pinpointing further differences esp. between the AppImage build and the system Qt. My first guess is that QWebEngine hardware acceleration is broken and blacklisted on your desktop GPU, but the Manjaro Qt package may fail to respect the blacklist. -- You are receiving this mail because: You are watching all bug changes.
