[PATCH xf86-video-ati] Don't enable DRI3 by default with EXA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michel Dänzer <michel.daenzer@xxxxxxx>

It doesn't work correctly in all cases, see e.g.
https://bugs.freedesktop.org/show_bug.cgi?id=95475 . I'm not sure this
is fixable, given EXA's architecture.
