Subject: [PATCH] glx: proposed fix for setSwapInterval
|
||
|
|
|
||
|
|
When mesa gets a DRI2 1.1 connection (as experienced with
|
||
|
|
vmwware DDX) we don't get a pointer for this.
|
||
|
|
|
||
|
|
Don't explode just keep going.
|
||
|
|
|
||
|
|
Fixes: 60ebeb4608a8 ("glx: Implement GLX_EXT_swap_control for DRI2 and DRI3")
