--- Comment #11 from andrei <akela1...@gmail.com> --- That would be interesting to try. I guess not only outline, but also brush drawing can be updated only in the area of brush. For now I just switched to Ubuntu, which does not have Nvidia Optimus. I read on some laptops it can be disabled in bios, but not on my MSI. I wonder how games for example work on Windows. If rendering is done only with opengl then intel gpu can be disabled...? hm... Maybe it's worth mentioning in some FAQ, that Laptop with Nvidia + 4K + Windows give noticeable lag. -- You are receiving this mail because: You are watching all bug changes.
