"Direct3D shared resources"-error despite disabled iGPU

Even though I disabled my GPU in my BIOS and in the Device Manager, I still get that error.

AMD Radeon HD 7950
Intel i5
(Edit) Motherboard ASROCK Z77 Pro4

Some people experience this problem when using ‘Action’ for example. Please figure out if you have other possible programs running it.

Thank you for your help. I disabled all Programms that could potentially cause issues(All Software related to capturing as well as Windows-Built-In DVR). It didn’t help. I still get this error:

I tried to run it on a new User-Account as well - didn’t work either. So I am pretty much out of ideas at this point.

This issue was resolved already.
