Fair point, but question is if it's software cursor from Xserver's perspective. NVidia driver might be blending the cursor in, while "emulating HW cursor" on the Xorg's end, right? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to

A recording would preferably be better, a screenshot might not give the full picture. Anyway, sure, I shall post it. The case I'm describing is more extreme, the squares are way bigger and flickering constantly, most of the time effectively preventing usage of the machine, such messy it gets.

Tested on Dell XPS13 (Intel GPU) and Precision M3800 (Intel/Nvidia-nouveau), with evdi-backed displays mostly focusing on enabling/disabling screens, both by system settings as well as ACPI events (lid closing/opening). Looks fine so far. -- You received this bug notification because you are a

Consulted the bug on #gnome-shell IRC. Next step is to track down the event that actually triggers execution of cogl_glib_source_dispatch. It's possible it simply does not arrive. BTW, this does not rule out Xorg as potential culprit, it might be simply not delivering the expected event. This

OK, I'm totally sure it's a freeze. Moreover, gnome-shell stack trace looks normal, event loop runs just fine. I can generate and provide core file if needed. What I managed to debug so far, is that in case of multiple /dev/dri/cardX being created frame_cb in meta-stage-x11.c:296 is not called
