--- Comment #5 from Boudewijn Rempt <b...@valdyas.org> --- Okay... It's to be expected that the appimage will be better on the same hardware than the windows executable, because windows adds a bit of a delay because of its compositor. But apart from that, 4.2.2 should be faster than 4.1.7 on the same hardware and os, because we did a lot of work optimizing brushes and the canvas. I don't have a Windows 7 system anymore, so I cannot check that, but on my Windows 10 Yoga laptop, 4.1.7, 4.1.8 (which is not a release, but a build I did of 4.1.7 with Qt 5.12) and 4.2.2 all perofrm fine. Maybe you could check 4.1.8 too? Then we can know whether the issue you're seeing is because of changes from Qt 5.9 to Qt 5.12.
