This is caused by incompatibilities between Qt WebEngine (used by the viewer and editor) and the graphics drivers
on your system. Try updating the graphics drivers, if that does not work, you can try disabling hardware acceleration
by setting the environment variable QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu"
