IF your gpu was weak enough before i removed the blur it could stutter. the darkening is cheap - it's rendering the large window previews in the zooming in popup of the switcher that is more costly (unless it's the blur which is even more costly...) it COULD have been the dither shader though too - i actually just optimized it tonight, but the i5-4200u i have here copes perfectly with it and silky-smoothly fades. if i tap alt-tab really fast it only partly fades in before fading out again... > (BTW, this is using the window switcher in list mode, not in large mode > where this whole background darkening is probably really necessary as > there is otherwise no window to separate the list from the normal desktop.) the darkening is cheap... it's just a big solid rect that is semi-transparent. rendering the miniature windows is going to cost more. are you software rendering? then this can get a lot more costly. it makes a MASSIVE difference in software compositing - like goes from 5-10fps to 60 if the window miniatures are not included in the list mode. the darkening makes really no difference (well in comparison). so my guess is - you're software compositing - you may not have even realised it. > Cheers and thanks as always for the great work, > Florian > > >> It doesn't happen in other more modern PC I have. > >> > >> I wanted to let you know because it looks like something happened > >> here.
