One immediate workaround to try is to set QT_XCB_FORCE_SOFTWARE_OPENGL=1 environment variable. Alternatively, https://copr.fedorainfracloud.org/coprs/kkofler/qtwebengine has some (admittedly hackish) patched mesa builds to workaround the issue of nouveau not supporting multi-threaded rendering (that webengine uses) too. there's also some discussion upstream at https://bugreports.qt.io/browse/QTBUG-41242 on alternative approaches, like "disable-gpu-when-using-nouveau- boo-1005323.diff" referenced there. -- Rex _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
