> Can you record a trace with apitrace that reproduces the issue?

I could, I guess.  I've never used the tool before, though, and have no idea
how to trim it to the relevant part.  I can't attach a 179MB trace file (109M
compressed).   I tried trimming to just the relevant region(s), but it's screwy
at best, and mostly garbage in the replay, I doubt it's useful.

> If not, which games are affected? What Wine version? Is CSMT enabled?

I dunno.  I erased my notes after I discovered at least 4 broken games; at that
point, I realized that these problems only started around the later tests,
where Mesa had been auto-updated to 17.2-some rc by my regular system updates,
so I stopped blaming wine and tried reverting Mesa instead.  The only ones I
still remember are KOTOR (because it was worst) and Chains of Satinav.  The
attached picture is from the former; I test the presence of the bug using the
latter, because KOTOR often has (unrelated) trouble starting up.  Note that
neither game shows this problem all the time:  Satinav only shows it in the
cursor when the cursor is over a selectable area, and KOTOR only shows it at
certain viewing angles (I don't really know what the difference is).  Both, and
others that had issues, displayed brief flashes of dot grids at various other
times as well.  I currently use Wine 2.0.2, 2.15, 2.15-staging, and
with/without gallium-d3d9.  I can assure you that I tried all combinations of
the above when I discovered it didn't work normally.  2.0.2 doesn't use csmt by
default, and 2.15 does, so apparently csmt doesn't make a difference.
