This appears to be caused by the UpdateSubResource call,
which is worked around by enabling the other image upload
path that ANGLE supports.

The workaround doesn't include a driver version, since the
bug is occurring in the most recent driver that is currently
available (15.40.42.5063, released 19th Mar 2019).
