Sorry, that's was a C bug.

I'm running mesa 18.3.0-1 and tested with 106052.95d62baac5-git.

Please test with a more recent version of Mesa before reporting bugs, otherwise
you are just wasting the time of developers (we already have limited
resources). You have an extremely odd setup, cutting edge Kernel with obsolete
Mesa versions (almost 2 years old).

Please retest with Mesa git or at the very least Mesa 18.3.

What I assume would help (like I said in the wine bug report), if it was tested
with other drivers. Sadly apitrace doesn't reproduce the problem, so it's a lot
more effort - and I don't have other drivers/hardware to test with.

Bug ID: 108985
   Summary: Visual Novel "The Fruit of Grisaia" has flickering
glitches
   Product: Mesa
   Version: 18.3
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/radeonsi

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=1 wine grisaia" makes the issue disappear.
- slowing wine down with "WINEDEBUG=+relay" log spam makes the issue disappear
- "vblank_mode=0"  makes the issue disappear (when not in fullscreen)
- LIBGL_DRI3_DISABLE=1 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 the 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
