Subject: WORKAROUND: turn off vid.support.ext_framebuffer_object if nonpoweroftwo is not suppo... 
X-Git-Tag: xonotic-v0.6.0~59
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=4ab71001a72e402ffdcec13a31f93ee6bb044166;p=xonotic%2Fdarkplaces.git

WORKAROUND: turn off vid.support.ext_framebuffer_object if nonpoweroftwo is not supported because FBO rendering with non-npot is currently massively broken

Please revert this commit when fixing the issue.
