Bug ID: 461001
Summary: Restoring cursor visibility fails with Blender on
Wayland with Tablet events
Classification: Plasma
Product: kwayland-integration
Version: unspecified
Platform: Archlinux
OS: Linux
Status: REPORTED
Keywords: wayland
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: ideasma...@gmail.com
Target Milestone: ---
On Blender, restoring cursor visibility fails, leaving the cursor entirely
hidden.
STEPS TO REPRODUCE
Note that I have worked around this bug in Blender, see:
- To reproduce this bug, use a Blender build without the workaround, SHA1
`c4f9e4afab8c51e271fc6a313ccd2dd0b8d3186c` (using Blender's source with `make
lite` is sufficient, or I can provide a build from our build-server if that's
preferable).
- The issue has been worked around in
`78b13ab3db70cca977585e29407445d2d1502fbf`
(https://developer.blender.org/rB78b13ab3db70cca977585e29407445d2d1502fbf),
which might give a hint to how this can be fixed.
**Exact steps for others to reproduce the error**
1. Load up default cube scene `blender --factory-startup`
2. Switch to the "Rotate tool" (on the left hand tool bar, 4th tool down from
the top)
3. Use a tablet to click on the rotate gizmo and do some rotation.
4. Position the tablet cursor so it is not on the gizmo when the tablet press
is released.
5. The mouse cursor is now hidden (UNEXPECTED BEHAVIOR)
OBSERVED RESULT
The cursor remains hidden on releasing the tablet press.
EXPECTED RESULT
The cursor should be visible (the default arrow cursor) when releasing the
tablet press.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.26.1
KDE Plasma Version: 5.26.1
KDE Frameworks Version: 5.99.0
Qt Version: 5.15.6
ADDITIONAL INFORMATION
- This seems like a bug as it only happens with tablet events, not mouse
events.
- This issue doesn't occur in Gnome-shell (mutter 42.5).
- This is the up-stream bug report: https://developer.blender.org/T102048
