Hi Guys!  
I’ve recently downloaded a new extension built to segment muscles from multiple types of data. Unfortunatelly I haven’t managed to run it succesfully with GPU. CPU works perfectly fine. The authors can’t repeat this error to make some investigation, whats the cause of this issue.  
And the issue is:  
“Segmentation completed” but model is not rendered.

Bug details below:

It seems like something crash during interpolate, maybe there is some “CUDA OUT OF MEMORY” error because I can see how GPU rises to 100% memory for a while during processing and then drops down to 0%. A few seconds later segmentation appears but in this pixel-thing form.  
I’ve restarted multiple times multiple versions of Slicer starting from 5.4.0 to the newest. None of them are willing to work on GPU.

Does anyone have the same problem, or had and got up with the solution ??

Best regards  
Bartek
