X11 and Intel graphics – occasional freeze with recent drivers.

Hi guys,

Has anyone else experienced a noticeable freeze (lasting between a fraction of a second to several seconds) in X11 with xf86-video-intel on an up-to-date Arch install? This seems more noticeable on less-powerful hardware, particularly my Netbook!

The multi-system emulator Retroarch really used to perform well (i.e. sustained smooth scrolling) under Arch, but now seems to lock up for a moment every 10-20 seconds. This only happens in full-screen mode with vsync enabled and it is NOT the emulator that is at fault. I have an older Arch install on a USB stick that works fine with the current build of Retroarch. Very strange indeed.

I know there isn't a lot of information here in terms of package versions, but I wanted to put the feelers out before I start churning through older versions of xf86-video-intel and X11 packages to narrow down the point at which this started.

This behaviour was introduced in xf86-video-intel-2.99.912-1. With the previous package - xf86-video-intel-2.99.911-2-x86_64.pkg.tar.xz - this did not occur.

EDIT: could this be related? :

Did v2.99.912 make the jump to DRI v3?

AFAIK, DRI3 is currently disabled in Arch packages. Check mesa and xorg PKGBUILDs.
