Bug ID: 469695
Summary: Drawing Tablet and Mouse Cursor are fighting for the
current Position
Classification: Plasma
Product: kwin
Version: 5.27.5
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: glados9...@protonmail.com
Target Milestone: ---
SUMMARY
The KDE Desktop didn't support Multi Cursor that well in X11 and in Wayland it
still didn't change. There is still one Cursor that every device is fighting
for. In X11 you can play with Multi-Pointer support while in Wayland you can't
except for the forced second Pointer of a Drawing Tablet.
Multi-Pointer in X11
https://wiki.archlinux.org/title/Multi-pointer_X
wl_seat and wl_pointer in Wayland
https://wayland.freedesktop.org/docs/html/apa.html#protocol-spec-wl_seat
STEPS TO REPRODUCE
1. Attach a Wacom Tablet (or any other Drawing Tablet)
2. Use Wayland KDE
3. Draw while you move your mouse
OBSERVED RESULT
1. Notice how the Drawing Tablet has its own cursor and the mouse too.
2. Draw with the tablet while you move the Mouse, it will create cool Patterns
in Xournal++ but its not how it should behave.
3. Notice how any seperate Cursor is actually fake and there is still only one
current Cursor that can interact with the KDE Desktop but two different saved
positions for each device.
EXPECTED RESULT
Like in Gnome, each Cursor should have its own Focus and work independently.
You should be able to focus both at the same time and Pointers/Cursor should
not Fight against each other.
Additionally, pls add support for KDE Wayland to put any Mouse into its own
Seat like you can do with xinput create_master in X11.
