Subject: st/xlib: Don't destroy screen on XCloseDisplay()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=feb71117aebc0932a96b548b4c402b010a008b2d;p=mesa.git

st/xlib: Don't destroy screen on XCloseDisplay()

screen may still be used by other resources that are not yet freed.
To correctly fix this there will be a need to account for resources
differently, but this quick fix is not any worse than the original
code that leaked screens anyway.
