Subject: [PATCH] Don't recreate hidden egl surfaces
|
||||
|
||||
QWaylandEglWindow deletes surfaces when a window changes from hidden to
|
||||
visible, presumably as a result of us not having a valid wl_surface
|
||||
object. By extension it doesn't make sense to create a surface whilst a
|
||||
window is still hidden.
|
||||
|
||||
This fixes a crash where a QQuickWindow hides and then is destroyed. In
|
||||
QQuickWindow destruction we have to create a valid context in order to
|
||||
delete any textures/assets owned by the scene graph; as the wl_surface
|
||||
has gone this causes an error in the EGL libs when we create an EGL
|
||||
surface.
|
||||
|
||||
Task-number: QTBUG-65553

||||
