--- Comment #10 from Nate Graham <n...@kde.org> ---
There's no Plasma code in the backtrace; it seems to be crashing deep in Qt.

The fact that you see different issues on Wayland suggests that there may be a
driver issue with the touchscreen itself that causes it to misbehave in
different ways depending on the environment's implementation.

FWIW I have a Lenovo ThinkPad X1 Yoga gen 4 with a built-in touchscreen that
also registers itself as a Wacom tablet, and it doesn't exhibit any of these
issues.
