Surely there MUST be a way in Painter to pause screen redraw? If there isn't, this is a much needed feature that should be implemented ASAP.
When dealing with heavy models with multiple UDIMs at 4k or higher, I'm having to wait for a slow redraw with every tiny change I make. Often I know I want to make several changes before I need to see the result, and the absence of any ability to prevent Painter from redrawing after every change just results in constant waiting and wasted time.
I have 256Gb of system RAM and a GTX 3080 with 10Gb VRAM, so this isn't a system problem.
