<pre>Under a guest VM running Gnome 3.26.2 Wayland, the mouse cursor becomes laggy,
and a double cursor (both host and guest I presume) when Mesa 17.3.x is
installed including the latest, 17.3.3. Reverting back to 17.2.8 and the
problem goes away.
In the system logs the following can be found:
Feb 03 22:03:19 lfs13 org.gnome.Shell.desktop[651]: Window manager warning: HW
cursor for format 875713089 not supported
I've done a git bisect:
e14fe41e0bf5d82c0b22eda2f8dcea058ac6e610 is the first bad commit
Tracking it even further, it seems to be related to __DRI_IMAGE being changed
from 15 to 17 in src/gallium/state_trackers/dri/dri2.c .
More info:
GL_RENDERER: llvmpipe (LLVM 5.0, 256 bits)
kms_swrast_dri.so
I wrote a simple test program, and the following function returns false under
17.3.3, and returns true under 17.2.8.

GBM_BO_USE_WRITE)</pre>
