Subject: [PATCH 15/24] UI: Destroy display when becoming invisible
|
|
|
|
When a window is made invisible, then visible again, the
|
|
obs_display is reused. Turns out, QT destroys the wl_surface
|
|
associated with the previewer on Wayland. However, the EGL
|
|
surface created on top of this wl_surface is not, and any
|
|
attempt to attach a new buffer to it will crash OBS.
|
|
|
|
Destroy the obs_display when becoming invisible, and when
|
|
running as a Wayland client. Also nullify the display
|
|
variable on destruction, to avoid subclasses double-freeing
|
|
the obs display.
