More or less safe reproducer for me: run a graphics-intensive 3D application
in windowed mode, and work normally with 2D applications for 10-20 mins in
the meantime. Though still not 100% reproducible....
I've given up trying to reproduce this. Anyway if the bug still is
present, it's a bug common to UXA and SNA so if it happens again, I
think it's better to start a new thread with a new title (and add me
in CC if you do, please).
P.S.: do you have any kind of powersave enabled? I had
«pcie_aspm=force i915.i915_enable_fbc=1 i915.lvds_downclock=1
i915.powersave=1» on GRUB and I removed them for further testing,
unfortunately that was around the time I started to being unable to
trigger it. I'm readding them just in case it's related.
