Texturize and Colorize not working

But I think I figured out the issue. It could be that I have an Asus ROG Flow X13 and a XG Mobile egpu that connects to it. It might be that the eGPU goes into sleep (eventough it shouldn’t) and then the system doesn’t have enough vram to complete the action. 

If this is the case, it could be usefull to display a message to the user stating that it’s the problem and not have nothing happen.
