Soldiers: Heroes Of World War II - flickering video playback

[WinterSnowfall]

The game hasn't worked up to Wine Staging 8.3 (not without patches), because of: https://bugs.winehq.org/show_bug.cgi?id=32235 , but a partial solution is now staged. The game still crashes at times, but is mostly functional.

3D rendering looks good, however there are 2 issues:

• game intro videos (those that are playable) and campaign intro videos flicker (this doesn't happen with WineD3D)
• There's a memory allocation error on startup, albeit the game seems to carry on just fine (setting a maxAvailableMemory limit doesn't do anything here, but it looks like WineD3D behaves the same so it might just be the game being dumb)

The memory allocation error is just the game being stupid, not something d3d specific.

As for the flickering videos, they might be related to partial presentation. They actually won't show up in the trace, so perhaps the game is using some other method of blitting them on screen.

Could be fixed by doitsujin#3392 . To retest after the next rebase.

The game crashes in game code after profile selection on latest main, after repeated:

warn: Device reset failed because device still has alive losable resources: Device not reset. Remaining resources: 1

Ok, #172 gets rid of the above. However, the videos flickering is still present... It could be related to multiple swapchain memes, I guess.

I always wondered why the game only shows up to "Medium" settings with d8vk/WineD3D and goes nicely to High on native Windows XP - turns out it reverted back to a "low video memory" mode when we reported too much VRAM. Fixed that now part of #199.

The game now refuses to start with dxvk master, but it may be due to an issue in Wine (it's happened before). Relying on use-after-free isn't ideal anyway, but I did have the game running rather well with the applied config options, with the exception of the videos, of course.
