Author Topic: Painter not responding on openning  (Read 1068 times)

As of this morning, substance painter is not functioning. When I open it it gives me a white screen that says (substance Painter(Not Responding) in the upper right and a completely white screen. Painter has been functioning normally since I started using it a week ago until this morning. I have tried restarting my computer and reopening the program.

Hello! I have the same issue with Substance Painter. Everything worked fine until 9th of april. Now I can't launch SP. I am getting white window (Not Responding) and don't have any chance to open my working files. Could anyone help with that problem please?

I'm not sure what of the following steps helped me to fix this issue but now SP v21 works correctly.
1) Install 2020 version then update to 2021
2) Turn off 2nd monitor in windows display settings

If the problem persists, could you share more information about your issue? What kind of hardware are you running on, what drivers do you have, your OS, etc.
