I noticed that sumu 1.1.1 on Ableton 12.2 - 12.3 saturates GPU memory usage to the point of crashing the DAW.
It uses all the available RAM in the system. ( 36Gb total )
If I instead set sumu to no-show, everything works normally again.
The error refers to:
NVIDIA OpenGL Driver, Error code: 6, An application has requested more GPU memory than is
available in the system.
The application will now be closed.
