Created attachment 871056 [details] SDL-1.2.15-no-default-backing-store.patch Apropos of upstream bug: https://bugzilla.libsdl.org/show_bug.cgi?id=2383 Since upstream apparently doesn't intend to do another 1.2 release, we should patch this back to the old behaviour, at least on Fedorae running xserver 1.15 or newer (ie, F21+). Attached patch does this.
Does xserver 1.15 always enable backing store, or only when Composition extension is enabled, or only if a compositor is running?
(In reply to Petr Pisar from comment #1) > Does xserver 1.15 always enable backing store Effectively yes, because... > or only when Composition extension is enabled ... when the Composite extension is enabled, backing store support is advertised, and the Composite extension is enabled by default.
I asked because your suggestion in the SDL upstream was to checke for a compositor, not for composite extension. At least that was my impression.

Yeah, I was trying to give them another option in case they really did have a reason to want backing store. I think just reverting to the old behaviour is the better move though. Thanks!
