I was not aware of that, I had considered gpl•3 'the best" license until now. I agree in so many points with the autor

Sadly not so much for me. Minimize/maximize animation stutters, mouse stutters if explicit sync is enabled (unrelated to min/maximizing, had to disable it), some windows dont maximize to the right size and hovering taskbar overlaps. I’ll have to look into it and maybe open bugs. Only used 6.1beta for a few hours so far
