relevant bits of dmesg
After resuming from hibernation, the screen freezes (flickers between two frames), and "Failed to initialize parser -125!" is printed repeatedly in dmesg.
Looks like a GPU reset was triggered during hibernation and that's what's causing the "Failed to initialize parser" error.
What chip is this? Please attach your full dmesg output.

I hiberate/resumed with this patch a couple of times, the problem hasn't occurred so far. Looks like this fixes the problem.
