Xorg.0.log with modeset error
I am using an Intel Ivybridge Mobile laptop with the git version of xserver.
When Option "PageFlip" is enabled (which is by default)I get
the following repeated error in xorg.log:
(EE) modeset(0): Failed to get GBM bo for flip to new front.
(EE) modeset(0): present flip failed
No such errors when page flipping is disabled in xorg.conf.
Same issue when using xorg-server-1.20.0.
Please see the attached xorg.log.
Same here on GTX770(GK104/NVE4).
Linux 4.17.2-1-ARCH #1 SMP PREEMPT Sat Jun 16 11:08:59 UTC 2018 x86_64 GNU/Linux
Same problem here. Also an Intel(R) Ivybridge Mobile chip.
xorg-server 1.20.1 (also present with 1.20.0)
mesa 18.2.0_rc2 (also present with 18.1.5)
I just now looked into the log. The problem probably exists some time longer.
