@umireon i'm still having a problem, and getting a strange error on the log

14:26:30.848: device_texture_create (D3D11): Failed to create 2D texture (80070057)
14:26:30.848: [obs-backgroundremoval] Failed to create alpha texture
14:26:30.853: device_texture_create (D3D11): Failed to create 2D texture (80070057)
14:26:30.853: [obs-backgroundremoval] Failed to create alpha texture

this error doesn't come up on the main version of the plugin.

so i think it's related to this change you're proposing here

[umireon]

@royshil Can you paste the full log here?

[umireon]

I could reproduced the problem on my side
