Do not harness backing store by default
|
|
|
|
xorg-server 1.15 enables backing store if composite extension is enabled
|
|
(default settings). Harnessing backing store through compositor leads to
|
|
tearing effect.
|
|
|
|
This patch reverts default harnessing backing store to conditional use if
|
|
SDL_VIDEO_X11_BACKINGSTORE environment variable exists.
