From 3af167185229afae754f86e1b86d6dd9a5acfb70 Mon Sep 17 00:00:00 2001 From: Marc-André Lureau Date: Tue, 16 Feb 2021 13:20:55 +0400 Subject: spice: flush on GL update before notifying client Since the introduction of spice/virgl support in commit 474114b7 ("spice: add opengl/virgl/dmabuf support"), the drawing isn't being flushed before notifying the client. This results in outdated/sluggish drawing on client side, in particular when using the Linux console.
