example of UI corruption
When I run World of Warcraft under Wine with Nouveau, the game has UI
corruption ranging from very mild (e.g. bits of text garbled here and there=
) to
severe (complete lack of UI whatsoever).
I recorded an apitrace trace[2] and when replaying on Nouveau, the corrupti=
ons
still do happen, complete with variations[1]. The same trace replayed on LL=
VM
(i.e. with LIBGL_ALWAYS_SOFTWARE=3D1) results with the UI being rendered 10=
0%
fine.
Running on the binary blob also does result in the UI being rendered 100% f=
ine.
I tested with two WoW versions: the [at the time of writing] latest 6.20 an=
d an
old 3.3.5a client =E2=80=93 both have the same kind of corruptions.
Do note that in some cases, the initial game "login screen" appea=
rs to look
perfectly fine; until one tries to e.g. enter one's login credentials or op=
en
the settings menu. So in order to tell if there are corruptions or not, sim=
ply
launching the game might not be enough.
[1] the corruptions seem to be consistent between runs (on both actual game=
and
trace replay) as long as I don't change anything window-wise. e.g. opening a
some program or moving some random window around results in different
corruptions each time while not touching anything and just re-starting the =
game
(or replay) results in very consistent corruptions.
I also noticed that when it comes to typed-in text (e.g. field to enter the
account name), the typed in letters seem to most of the time contain bits f=
rom
other portions of the screen outside of game's window.
