[PATCH 2/2] spice: flush drawing before notifying client |
Date: |
Tue, 16 Feb 2021 13:20:56 +0400 |
From: Marc-André Lureau <marcandre.lureau@redhat.com>
This solves the client having slow/outdated VGA/2D console. It's a
regression introduced when the code was switched to render it via opengl
in commit 4423184376d ("spice/gl: render DisplaySurface via opengl")
Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>
