Public bug reported:
I decided to try wayland and got several issues, in the order of
(subjective) importance:
================================================================
### Issue 1
I have two monitors, one of which is rotated 90 degrees, so I tried to set them
up in wayland session (as I did in X). You can see on the screenshot
"wayland_display_settings.jpg" that I specified that it is rotated and pressed
"Apply", and one of them *is* rotated on the preview.
However, you can see that actual content on that display is not rotated.
Also, note where the task panel is located on the first display - it is in the
centre of the screen.
Just in case, here is xrand command I am using in X:
xrandr --output DP-2 --mode 3840x2160 --pos 0x790 --scale 1.1875x1.1875 \
--output DP-0 --mode 3840x2160 --pos 4560x0 --rotate left --primary
================================================================
### Issue 2
It looks like some options are missing. In X, there are:
* "Replica of: None" option, which disables duplicating of image.
* "Primary" checkbox, which removes panel from secondary display.
but there are not such options in Wayland.
================================================================
### Issue 3
Scaling deteriorates sharpness, makes thin lines blurry. See screenshot
of Krusader 125scale_vs_100scale.png. Thin lines become blurry.
I was using this short guide to setup Wayland:
