On v0.32.0 and current master of 5a219bc, some surfaces are not drawn on Intel HD driven by Mesa 10.3.1:

A similiar issue seems to be #445. Pinging @gimhael to have a look.

Downgraded to Alpha 31 and 30 to test and this bug still appears. My efforts to downgrade Mesa were not successful. Will need to file a mesa bug.

[DolceTriade]

Turns out overwriting the i965_dri.so library in /usr/lib/xorg/modules/dri with an older version is sufficient to get the game running again. Also, filed a bug on the Mesa bugzilla.

Apparently this only affects linux.

@DolceTriade Any idea how we want to tackle this for the coming release? Do we know someone at Mesa whom we can lobby?

I have the same issue with Intel Graphics. See #478 and https://www.youtube.com/watch?v=jACO53o1CwU

Thanks filling the bug upstream. I added a "me too" comment, and made the video accessible.

@DolceTriade could you please tell which version your downgraded to in order to workaround this?

BTW, is there any known workaround beside downgrading?

[DolceTriade]

I believe 10.2.x will work fine.

[DolceTriade]

Updated freedesktop bug with commit bug was introduced and a hacky "fix".

[DolceTriade]

A proper fix will be uploaded shortly (to the mesa repo). Will close when the fix is comitted.

[DolceTriade]

Fix is comitted. http://cgit.freedesktop.org/mesa/mesa/commit/?id=c633528cbac007a73a066f269b3c9a25daf1e21a

For reference as I keep looking at this issue, Mesa 10.3.* and 10.4.0 are affected, 10.2.* and 10.5.* are not. Unsure about 10.4.n for n > 0.
