Subject: [PATCH] mi: don't call UpdateSpriteForScreen if we have Xinerama enabled. #18668
|
|
|

|
|
|
010d2eb |
In Xinerama all windows hang off the first root window. Crossing the screens
|
|
|
010d2eb |
must not reset the spriteTrace, otherwise picking fails and events are sent to
|
|
|
010d2eb |
the root window.
