The Steam Deck uses Wayland. Mint uses X11. That could be making the difference for the Vulkan version.
That and the 6770 is an old card, so it could be that the DX11 translated to Vulkan better takes your card's particulars into account than the native Vulkan backend does.
This should be less the window server than the gfx API at play. I'd say force DirectX if you think that looks better visually.
I'm getting similar issues with a 7900xtx in vulkan (distro is guix). So I'ts definitely not the age of the card. I tried messing with the settings and have been unable to fix it.
Maybe switching to dx11 is the trick here? I haven't tried it yet.
Yeah, worth a shot. Personally I had more graphical errors on DX11 with my 6700XT, but it definitely seems to vary by card
The Radeon 6770 is WAY below the minimum requirements of Baldur's gate 3, it's a miracle you even got the game running at all...
Vulkan API in that game is broken on both Windows and Linux. You're better off using DX11 on Windows or DXVK on Linux.
