[Intel-gfx] Skylake / (EE) modeset(0): present flip failed loop

[Marc MERLIN]

I hate to spam, but I'm still getting half a gig of errors in my logs
per day, to the point that I need to prune them aggressively, and
obviously Xorg with the new kernel and new intel driver, is not working
right.

If this is not the right place to get support, where is it?

If it's the place baring other options I haven't found, please help:

As per my last post:
I'll try a more basic question: am I supposed not to use the modesetting
driver if I want a working setup?
While debian seems to default to or kind of force the use of the modesetting
driver, if you confirm I shouldn't be using it, I can look at how to switch
away from it.

Thanks,
Marc
