I’m trying out some grease pencil drawing with a tablet, which means I spend a lot of time hitting undo. But each undo takes ~4-5 seconds, which is far too long to have drawing be viable. My scene is not particularly complex: 130k verts, no subsurfs on, no other performance issues. No lag when posing with my character rig. Undo occurs instantly in edit mode on mesh, but is slow on grease pencil in both edit and draw modes. It is also generally slow in object mode. And it was instant in pretty much every way on this same character back in 2.79.
Is there anything I can do to improve this? I’ve got Global Undo on. If I turn it off, then undo doesn’t work in Draw mode at all.
