I am an alpha tester for gnome next and I loved overall experience. But Still, I notice a few bugs.
I.Wayland
--------------------------
Wayland Compositor has the most bugs. The bugs I found are
1. Mouse pointer is not showing in desktop(A somewhat glitched square like thing is shown) but it is shown in Apps

2. Settings apps is not at all opening in wayland.
II. General Problems
----------------------------------------
1. Settings App crashes when opening mouse settings or Accessibility or something like that
2. A blue colour is shown instead of default background.(I dont know it is a glitch).
3.Tweaks Apps is not opening
4. Boxes are shown instead of japanese characters.
5.Once settings app crashes, it wont reopen.
6. Coloured pixels are shown for a fraction of second when exiting full screen in VLC.
7.Optimizations need to be done to improve performance
