Monitor
Product: plasmashell
Version: 5.25.0

Versions of KDE and plasma packages
SUMMARY
I have a ThinkVision M14t: It is a USB-C monitor with touch and stylus input.
https://www.lenovo.com/us/en/p/accessories-and-software/monitors/office/62a3uar1us
Since upgrading Plasma to 5.25.0, whenever I use touch to click anything on a
plasmashell panel (application menu / task manager / quicklaunch) plasmashell
just segfaults. I do not have that problem when I use the stylus to click
things.
Other applications (xournal / browser / onboard) react to stylus and touch
without any issues.
I can provide core dumps from the crashes, but they are larger than the
attachment file size limit.
I also ran plasmashell from a terminal with --replace and will attach the
output.
STEPS TO REPRODUCE
1. Connect above mentioned monitor
2. Interact with plasmashell through touch (not stylus)
3. Plasmashell segfaults
OBSERVED RESULT
Plasmashell segfaults
EXPECTED RESULT
Plasmashell should not segfault
SOFTWARE/OS VERSIONS
OS: Arch linux 5.18.5-arch1-1
Qt Version: qt5-base 5.15.5+kde+r163-1
I couldn't really figure out which package versions exactly are needed w.r.t to
KDE and Plasma, so I will attach a whole list as a file.
