Xorg core dump backtrace
Sorry, I need a full-debug log for this one. Judging by the explanation and trace, I would say that we have a pending swap that isn't being cleared across the mode change. I need to dig out why it wasn't flushed - or find the right reason. Created attachment 123845 [details]
DDX full debug log
As requested. :)
Apparently disabling TearFree causes this issue to disappear as well .. Looks the same assert as (should be) fixed by: commit 46ffdf295d161a70459508ef0643d70af66ed990 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun May 22 18:31:50 2016 +0100 sna/dri2: Avoid chaining swaps across a mode change If the pixmap on a drawable changes between swap events, just queue a normal vblank event rather than chaining up.
