Ditto, I wouldn't quite say it flies on my M1 MBA, but performance is by no means frustratingly laggy. I use Inkscape a lot on both my MBA and Surface Laptop and it is much more frustrating on the latter device. The lack of support for fractional scaling is an annoyance on my 150% scaled Surface. The tiny UI has to be remedied by pinning a .bat to my taskbar and disguising it as Inkscape, with the following code:
cd <Inkscape directory>
set GDK_SCALE=2
start inkscape.exe
And within Inkscape using the Minwaita-Inkscape theme and 80% font scaling to scale back the otherwise-now-too-big UI.
On both my Mac and PC, the main frustration once the UI is scaled correctly is that often closing pop-up windows (i.e. Document Properties) simply doesn't work. Sometimes using Inkscape's tab close button rather than the MacOS/Windows close window button works, but other times the whole app will freeze up and crash when attempting to close these pop-up windows. Have had this issue for multiple Inkscape versions now, hoping the devs find a way to fix it.
