Theoretically it is, but on one Linux computer I have it freezes from time to time, whereupon it stops redrawing frames, resizing the window results in gray rectangles etc. I think it’s caused by a slower disk, which is sad, because I don’t think that’s a legitimate reason for a UI to stop working. I can accept having to wait when opening a file, but the UI completely freezing is unacceptable. I typically close and open it again in those situations. It still has a faster fuzzy file search than anything available in Emacs, which is why I stick with it.
