[regression, d3d9] Supreme Ruler Ultimate alt tab render freeze

[Blisto91]

Since commit 52ac271 when you alt tab in Supreme Ruler Ultimate the renderer will freeze and not snap out of it when you focus on the game again.
Note that the commit itself will show the game as only a black screen, which is fixed a couple of commits later, but i can see with the dxvk hud not updating that it should be the one.

d3d9.deviceLossOnFocusLoss does not make a difference.

Software information

Supreme Ruler Ultimate

System information

• GPU: RX 6800
• Driver: few days old mesa main
• Wine version: Proton Experimental
• DXVK version: 52ac271 and up

Apitrace file(s)

Two traces where i go to the main menu then hover back and forth on the buttons -> alt tab -> hover back and forth again before quitting. One made with dxvk master and one made with wined3d.

Observe that when replaying with dxvk before the commit, e.g. 2.2, that the wined3d one will show me hovering over the buttons fine the second time after alt tabbing where as the dxvk one will end early before second attempt. When replaying with dxvk including the commit, e.g 2.3, both traces will end early and not show the hovering after alt tab.

I strongly suspect this is a game bug. The game leaks a state block in both the WineD3D apitrace as well as the DXVK one.

I've also written a quick test to verify that this will indeed make D3D9Device::Reset fail.

Replaying the WineD3D apitrace with the Windows Nvidia D3D9 driver makes Apitrace complain about the reset call failing.

Lastly, there's this: https://steamcommunity.com/app/314980/discussions/0/1652171126118360822/
