Subject: [PATCH] gdk: Clear GL context when window is withdrawn
|
||
|
|
|
||
|
|
Some clients (e.g. gnome-online-accounts) quickly unmap and map
|
||
|
|
a window. With some backends the backend surface will be replaced
|
||
|
|
causing the application to crash because the GL context is still
|
||
|
|
using the old surface. Clearing the GL context when a window is
|
||
|
|
withdrawn fixes this.
