PixelOver 0.8.0 was working fine, but after updating to 0.8.1, I just create a new project(2D Layer 256x256), memory usage reached 17 GB and PixelOver is very slow.
Hey, strange seems your canvas max size is really big. 256x256 it's the white rectangle, when I see the scrollbar it's at least 10k of canvas max size. Can you check please by selecting the canvas ?
