Subject: [PATCH 29/52] Do not update the mask if we do not have a surface
|
|
|
|
mMask serves as a cache to remember what we've sent, the source of truth
|
|
for the value is window()->mask().
|
|
No need to store values that we are going to discard, because it will
|
|
confuse the state of newly created windows.
