Interesting Firefox has similar warnings as DING had before. That suggests the bug is either in GTK or the graphics driver. Rather than being a DING or a Firefox problem.
As for the screenshot in comment #12, make sure you're never suspending the system, switching users or even switching VTs. Because all of those can cause the Nvidia driver to lose textures, which is covered by bug 1876632. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2004533 Title: very unstable desktop, icons vanish, cannot control windows, cannot resize or scale multi monitors easily.
