alt Hacker NewsWhen I upgraded from Debian 12 to 13 on my personal laptop running KDE, I knew that the switch from X11 to Wayland would happen and was braced for all kinds of issues, like every other time I tried to switch to Wayland in previous years.
Instead, I could tell literally no difference. Multiple desktops works fine, scaling works fine, screen capture works fine, old apps work fine, literally everything works just fine.
Good job, KDE team.

I think I noticed lower latency, more consistent frame pacing (recent-ish improvement in KWin) and a more "solid" feel because everything in a frame is synchronized. On X11, you can have things like border and contents of a window not matching exactly while resizing. An early principle of Wayland was "Every frame is perfect", which is clearly reflected in how e.g. window resizing works.
I recently installed Kubuntu 26.XX on my desktop, was worried about having to use workarounds and giving up on fractional scaling to use it with my NVIDIA gpus (previously had to do this), but was also pretty surprised that it has been smooth sailing.
For the records, Debian 13 Gnome with Wayland works as well as with X11. The only reason I'm still using X11 is that backlight control doesn't work anymore with my old laptop (it did with Debian 11) and X11 can work around it with gamma correction and Wayland can not.
On the other hand, I recently installed a system with debian 13, and it was really easy to distinguish between X11 and wayland sessions: if the session displays a plasma desktop, it's X11, if it crashes on login, it is wayland. YMMV if you try to switch to wayland.
