Yes, I tried a tiling window manager for about an hour and then stopped. It was absolute madness as the window size and positioning was seemingly random. I can't comprehend how anyone can use them
Tiling window manager means relying heavily on workspaces. You distribute the windows over workspaces.
And most algorithms for management are deterministic. The position and the size of the new windows is always known.
Used to use AwesomeWM for almost a decade before I forced myself to simplify to Gnome for other reasons, but I never felt like window sizing and positioning was random, it always opened in the logical place, which I kind of feel like is the whole value proposition of a window manager in the first place.
For curiosities sake, what window manager did you try?
