Subject: [PATCH] ANGLE: Do not reset the share handle when resetting the swap
|
||||
chain.
|
||||
|
||||
This change only affects the ANGLE_surface_d3d_texture_2d_share_handle
|
||||
extension. The patch is necessary to have WebGL running in Qt/WebKit2.
|
||||
|
||||
If the share handle is reset, we are loosing the reference to the
|
||||
EGLSurface and cannot actually reuse it in a different context anymore.
