Fullscreen does not show in World of Tanks

[FerromagneticCompound]

World of Tanks fullscreen window does not appear. Playing in borderless window at full screen resolution works well, but when one starts the game in fullscreen mode OR change from windowed mode to fullscreen mode, the game window disappears. The game appears to still be running, although no window is shown.

Steps to reproduce:

• Run installer
• Start game through launcher
• Game window fails to appear (default start option is fullscreen)

The game performs fairly well even when running windowed, so great kudos to you Doitsujin :)

Question, does it work with wined3d?

In general I'd recommend sticking to borderless fullscreen for DXVK in general, there's a ton of bugs related to fullscreen mode and it's nigh impossible to even debug them.

[FerromagneticCompound]

Interestingly, fullscreen works with wined3d in the old Wine 2.21, but the game fails to start in the 3.x series. DXVK to the rescue! ;)

I can imagine the problems with debugging these issues. Is there anything I can do to help?

Can you retest if current master still shows the issue, there is a dxgi fix in which might be related.

[doitsujin]

@pingubot just because I fixed one DXGI issue doesn't mean that I fixed all DXGI issues. This one is unrelated.

[doitsujin]

Please test if this is still an issue.

It appears to still be a problem with the following:

• Wine 3.15 (esync)
• Mesa 3.2-rc5
• DXVK 0.71

Output at startup:

info:  Game: WorldOfTanks.exe
info:  DXVK: v0.71
warn:  OpenVR: Failed to locate module
info:  Enabled instance extensions:

info:    Vulkan: 1.1.70

Same behaviour as previously - Windowed mode seems to be working fine - I'll also test without DXVK, and edit with my findings.

For me, fullscreen mode does work, it just minimizes itself on start, so its not visible. I just repeatedly click on the GNOME taskbar button for World of Tanks until the game shows up properly. Takes a few clicks. I guess its still an issue though, because this shouldn't happen.

[doitsujin]

DXVK doesn't minimize or otherwise interfere with the game window though, so that issue is likely caused by something else.

[viggy96]

@doitsujin Yeah, I just wanted to mention it, just let you know that fullscreen does work in that game. Just has a small quirk, and I don't know what is causing it.

that looks like some mutter bug that was workarounded in Proton.
