Bug ID: 496048
Summary: Wacom tablet causes KDE Plasma to crash, including
related applications
Classification: Plasma
Product: plasmashell
Version: 6.2.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: degenn...@gmail.com
Target Milestone: 1.0

The backtrace produced by Dr. Konqi
SUMMARY
My Wacom Intuos CTH-490 works perfectly fine on KDE Plasma on Arch Linux.
However, if the tablet is disconnected (whether via the wireless receiver,
turning off the tablet while the wireless receiver is plugged in, or simply
unplugging it while connected via the cable), plasmashell (and a whole bunch of
other KDE Plasma-related services crash and Plasma restarts. Also, I do not
have to use the stylus itself. Connecting and then disconnecting it is all it
takes to crash the desktop.
I'm not sure why this happens, and I'm very sure this isn't just my Zephyrus
GA401QC (or its RTX 3050) being weird as usual, because the behavior also
appears on my second laptop (Ideapad 3 14ADA05). The issue presents itself on
Fedora too. This has never happened before the, I believe, 6.2.2 update for KDE
Plasma. The behavior is consistent; everytime I disconnect my tablet (if it's
been properly connected, of course), everything crashes. No exception, unless I
plug it out as soon as it's been plugged in.
Of Note: Non-KDE applications do not crash Ever. Firefox, Spotify, Steam, etc.
all continue running as if nothing happened. Also, the other KDE apps also
backtraces as well. I don't know how similar they are to each other though, but
I can include them if need be.
STEPS TO REPRODUCE
1. Plug in Wacom Intuos CTH-490, probably give it a second or two
2. Unplug it, whether through the USB cable, the USB receiver, or turning the
tablet off via the wireless module while still connected to the receiver
OBSERVED RESULT
Everything KDE related crashes. The desktop environment, Settings, Konsole,
Yakuake, Discover, and Dr. Konqi (if it was open prior to me testing the bug)
all crash. Non-KDE related applications do not crash, however.
EXPECTED RESULT
Plasma working as usual.
