Hello, thx 4 the awesome tool.

I tested it on Linux Mint 17.3 Cinnamon and there are huge lags of performance.
My Hardware: Intel Core i3-440, Nvidia GT 640 2GB, 8GB DDR3 RAM.

I checked Krita in one VM (Windows7) too and and have way less lags there.
Maybe the hardware acceleration does't work in Linux in my case?

No, you have both OpenGL enabled as well as AVX for vectorization. There must be something else going on your system: also, what is the colorspace and channel depth and image size you are working with?

RGB - 8-bit

1440*1440 - 10-15 layers (import a psd-file)
