What problem did you encounter?

When using a fresh, v1.9.1 prefix created by Vinegar, the default WineD3D renderer is OpenGL. On my end, however, the OpenGL renderer simply doesn't boot - at least, the bootstrapper and engine start up, but nothing is displayed. The following log attached is an instance of this behavior occurring, all with a fresh cache.

Setting the renderer requires manual intervention, either through regedit or Winetricks as typically used to switch the WineD3D renderer. vulkan works fine, and so does gdi (as well as no3d, due to it being an alias).

It might be a driver issue on my end, but I've had native OpenGL applications run fine as well as games run through Proton, so I'm unsure on what might be wrong here.

The flickering issue DXVK has at the moment prevents me from using that.

I'm unsure of what's the proper system information program typically used in the issue tracker, since this is my first issue, but below is a (partially modified to remove the hostname) output to inxi -CGS:

This appears to be an issue with Wine 10.16 and Nvidia. I would bisect the commit that caused this issue to appear, but I don't have an Nvidia GPU, so I can't really do that.

That's interesting. I don't think I've had this issue before in other applications, but it might be because I use Wine and its derivatives for gaming and thus use either Steam's Proton or Proton-GE alongside DXVK (which is not acceptable at the moment for Vinegar due to the issue I mentioned above), so this is the first time I see this issue.

Steam's Proton and Proton-GE are currently based on Wine 10.0 Stable and not on any development versions (10.1, 10.2, etc.) like the one that is shipped with the Vinegar Flatpak.

Also, the flickering with DXVK is an issue with Wine's Vulkan renderer on top of its X11 driver. This issue does not occur with Wine's OpenGL renderer or with its Wayland driver, though the latter isn't fully stable yet.

Obviously, there has been some sort of regression in one of the development versions which caused WineD3D's OpenGL renderer to not function under Nvidia graphics, at least with Roblox Studio. I've discussed this with a member of the Vinegar Discord server and they are planning to bisect the commit that caused this issue for me, since I don't own an Nvidia GPU.

Ah, that makes sense, then.

Also, the flickering with DXVK is an issue with Wine's Vulkan renderer on top of its X11 driver. This issue does not occur with Wine's OpenGL renderer or with its Wayland driver, though the latter isn't fully stable yet.

I can confirm that, using the Wayland driver and directly launching Vinegar, the flickering does not occur.

Also, I only now found this out, but from the looks of it, WineD3D using OpenGL on Wayland in my case appears to work fine. The only tradeoff is the improper window decorations, and a lack of resizing and dropdown menus. I'll update the issue title to mention the X11 driver, since I only now found this out myself.

It's possible to change the desktop entry to unset the DISPLAY environment variable and do this from the command line, although the manager doesn't appear to carry this behavior properly, so that makes it somewhat unusable for launching Roblox Studio.
