Subject: [PATCH 10/36] Fix leaked subsurface wayland items
|
|
|
de89c0 |
|
|
|
de89c0 |
Whenever a subsurface was added we would create a QWaylandQuickItem,
|
|
|
de89c0 |
but this was never deleted. It is one-to-one with the surface, so it
|
|
|
de89c0 |
should be deleted at the same time.

[ChangeLog][QtWaylandCompositor] Fixed a memory leak when creating
|
|
|
de89c0 |
subsurfaces.
