Description:

I ran Hedgewars in a separate X server:
[code]xinit hedgewars -- :1 vt$XDG_VTNR[/code]
I start a quick battle with an AI. When the battle view is reached I experience awful screen tearing. When I ran the game through the DE, (Cinnamon) everything is ok.

This was observed using 1:2.99.917+703+g15c5ff1-1
This doesn't happen with xf86-video-intel-1_2.99.917+604+gff0ab2c
If the package is downgraded, the issue disappears even without a reboot.

The same behavior is observed if the rendering method is switched back to DRI2 from the default DRI3.

Let me know if I should report this upstream.
This task depends upon

Please try the latest version in testing. If it is still broken please file an upstream but and feel free to git bisect.

Tried with xf86-video-intel-1:2.99.917+708+g8f33f80-1-x86_64, behavior the same.
I guess the old version used DRI2, so it's probably a problem with DRI3

I'm reporting upstream, will put the link here in a while.
