Screenshot showing a glitch

This is a bug about a game run in wine. I've already submitted a wine bug, =
but
after a lot of testing I assume it's more likely a mesa bug.

When played, the game as flickering/glitches where sometimes an old scene is
partially shown over the current scene.

What I found out so far:
- apitrace always plays back perfectly fine
- "LIBGL_ALWAYS_SOFTWARE=3D1 wine grisaia" makes the issue disapp=
ear.
- slowing wine down with "WINEDEBUG=3D+relay" log spam makes the =
issue disappear
- "vblank_mode=3D0"  makes the issue disappear (when not in fulls=
creen)
- LIBGL_DRI3_DISABLE=3D1 makes the issue go away
- usage of gallium nine makes the issue disappear


As I said, not sure where the fault is, but I can provide more information =
if
needed.

There's also a demo if you want to reproduce yourself:
http://suezou.dyndns.org/dl2010/frontwing/gurizaia/Grisaia_trial_=
web.zip (700MB
and might take a while to download)

Guide to test:
0) Get the demo
1) Click through the installation. It installs to
"C:\frontwing\SomeJapaneseFolder"
2) run wine "Grisaia", it opens a dialog where you should click t=
he right
option (windowed mode)
3) in the main menu click the first option, and then any of the scenes you =
can
select.
4) Press left-ctrl to fast-forward or the mouse to advance
5) 5) Screen tearing is pretty obvious (see attachments)


System the bug was tested on:
- Arch Linux 64bit
- Linux 4.19.08, AMDGPU driver
- Mesa 17.2.0-devel (git-ccf9669cc1) / Mesa 17.0.5
- Radeon R9 285
- KDE Plasma 5 with OpenGL compositor and regular X session
