From 25db875401c8aaac31a6650cb80a56cc78852694 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Tue, 16 Jan 2018 08:54:30 +0100 Subject: [PATCH] drm/vmwgfx: Cursor update fixes Use drm_plane_helper_check_update also for the cursor plane. Some applications, like gdm on gnome shell still uses cursor front-buffer like rendering without notifying the kernel. We do need some kind of noficiation, but work around this for now by updating the cursor image on every cursor move.
