xorg.log

After some uptime, I see my desktop flickers heavily. I have 2.99.917-307-g3852977f14a0 atm.

video demonstration

Demo of what is going on. This is a white terminal and I switch virtual desktops up and down.

The video is slowed down 10 times.

And note that the terminal is set "visible on all desktops". Hence it is still visible wherever I switch. Anyway it flickers now which was not happening after I started fresh X session.

That's more likely to be an external issue. mtbf suffiicent to be able to test drm-intel-nightly (or linus)?

Very likely. Suspend+resume fixed that.

It's very hard to reproduce. With 4.0.4, I have seen it once until now. Let's see.
