Subject: [PATCH] backend: Clean up renderer after clutter backendm
|
|
|
1a7f9f |
|
|
|
1a7f9f |
commit c4a73e795020722eda3e2bec0c16d96f9f37333b added
|
|
|
1a7f9f |
code to cleanup the renderer when the meta backend is
|
|
|
1a7f9f |
disposed. Unfortunately, this introduced a crash when
|
|
|
1a7f9f |
the window manager is replaced.
|
|
|
1a7f9f |
|
|
|
1a7f9f |
This is because cleaning up the renderer involves talking
|
|
|
1a7f9f |
to the X server over a display connection that's closed
|
|
|
1a7f9f |
two lines higher as part of the clutter_backend_destroy
|
|
|
1a7f9f |
call.
|
|
|
1a7f9f |
|
|
|
1a7f9f |
This commit fixes the crash by swapping their order.
