Roblox has a texture problem

[AshtakaOOf]

With the wine from winehq everything work fine except the mouse being stuck in the middle of the screen so i tried to use wine tkg like the roblox fandom said and apply the roblox mouse patch. But now the game has completely broken texture it can missing texture completely plain color or weird vaporwave looking texture, the game is still playable but more i play more the texture change and bug, i would use winehq if the mouse wasn't locked in the middle of the screen. So i took a screenshot to show an example of what happen. If someone can help i would really appreciate it !

my os and specs: Fedora 34 Amd ryzen 7 5800h RTX 3070 laptop 16 go ram ddr4 3200mhz and 500 go ssd also 3200mhz

In the screenshot i added some little indicator of what bugged, the sky and the squad player counter. When i join a game on blackhawk 30% to 70% of the texture are bugged on other game 30% to 40% of the texture are bugged

on defender depot there are only missing texture this time

With the wine from winehq

I assume mainline then and not staging? Since wine-tkg will default to staging, there might be some wined3d patches in there breaking roblox. If your machine supports vulkan, you should use dxvk instead of wined3d and it should fix pretty much all visual issues.

If it doesn't, you can set the _use_staging options to "false" to use mainline wine as your base instead of staging.

winehq wine 6.18 staging and how can i set it to use dxvk ?

Unfortunately I can reproduce graphical issues as well.

I've tried using both wine staging and normal wine and there seems to be no difference there.

When using Vulkan (by changing the grapejuice prefix through winetricks to use the vulkan renderer), it seems to fix some of the issues but my performance DROPS incredibly. Compared to vanilla wine with Vulkan which can run comfortably at 50+ FPS, this fork struggles to maintain 10 FPS.

Is there a configuration that could help stop this performance hit?

Alright so the solution involves having to modify a FFlag in Grapejuice to make Grapejuice prefer the Vulkan renderer.

You'll want to turn on "FFlagDebugGraphicsPreferVulkan" and that should improve performance.

UPDATE: You'll also want to enable "FFlagFutureIsBrightPhase3Vulkan", especially for games that use the "Future Is Bright" lighting such as the Chipotle game. This will stop huge performance hits in relation to that lighting system.

Also, staging 6.0 wine with the updated server-default_integrity/0007-ntdll-Elevate-processes-if-requested-in-RtlCreateUse patch and the roblox fix/mouse fix patches, and the childwindow-011fabb patch and josh flat theme patch, does not have this issue. Nor does any recent non-tkg wine staging versions such as v6.20.

Edit: I may or may not be wrong about the recent wine staging versions, I haven't really tested them. nor do I have the time to test them.
