Subject: GLX: Fix desktopfullscreen size when we actually switched to it.
X-Git-Tag: xonotic-v0.8.0~126
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=646f09b960301e15996fe91c8c541191888c085f;p=xonotic%2Fdarkplaces.git

GLX: Fix desktopfullscreen size when we actually switched to it.

Should fix a few possible issues with getresolution(-1) on a multihead
setup with some window managers.

Also, remove a superfluous memory allocation on GLX when not using
DPSOFTRAST.
