Start with posting DXVK logs.
How can I get these logs?
Hi there. Dxvk does indeed not support direct composition.
In regards to VST Plugins specifically then we are already tracking the issue at https://github.com/doitsujin/dxvk/issues/4968
It's using DirectComposition which both DXVK and Wine don't really support yet.
Try running it with DXVK_CONFIG="dxgi.enableDummyCompositionSwapchain=true" but that might not work. It's a bit of a hack.
(Blisto was faster)
DXVK_CONFIG="dxgi.enableDummyCompositionSwapchain=true"
Same behaviour.
Then there's nothing we can do for now.
Alot of VST plugins that rely on DXVK stuff is showing a completely blank GUI.
The paremeters of plugins can be controlled through a interfaceless method and the sound process is working as intented.
Software information
It can be tested with any free plugins of this page on a new WINE prefix and DXVK installed through
