Bug ID: 465881
Summary: [Drawing tablet]: Panel can become unresponsive to
hover events when using a stylus
Classification: Plasma
Product: plasmashell
Version: master
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: [email protected]

Target Milestone: 1.0
SUMMARY
The panel can become unresponsive to hover events when hovering items while
using a stylus. This issue happens on both X11 and Wayland, but it behaves
differently in both sessions.
On X11, when window thumbnail tooltips appear, if you keep the cursor inside
the panel and move around, the tooltip will stay open for a while (see BUG:
465650), but all other hover events will get "eaten" when )and after) that
happens, including while hovering over other items on the panel, like when
trying to show tooltips on the system tray.
On Wayland, hovering works fine until you interact with an application and come
back (tested with Firefox (Xwayland) and Dolphin (native Wayland)). After you
move back to the panel, nothing gets hovered anymore, and highlights of icons
that were activated stay stuck until you use a normal mouse.
I will attach two videos, one for X11 and another for Wayland.
STEPS TO REPRODUCE
Wayland:
1. Open an application with a stylus, like Firefox
2. Interact with it with the stylus
3. Hover with the stylus over the panel, nothing will respond to hover.
Clicking on the panel again with the stylus sometimes fixes the issue.
X11:
1. Hover over window thumbnails (if you can't reproduce, it helps if you click
on the icon of an open app first with the stylus)
2. While still hovering the panel, move around (do not move the stylus outside
of the panel!)
OBSERVED RESULT
Hover events are not respected on the panel, icons look stuck and no tooltips
show up
EXPECTED RESULT
Should work the same way a mouse works
