The issue only shows with Age of Wonders II and AoW Shadow Magic.

Every version of wine from 0.9.55 to 0.9.58, including several
intermediate git builds.

Xorg version 1.4.0.90, and a couple other versions (the problems has
persisted across a couple updates of Xorg)

Hardware rendering; using the prop. nV driver; updating that also
doesn't affect the issue, nor does retaining the same version.
