[Vinay Keerthi K T (stonecharioteer)]

I faced the same problem with Konsole. It crashes when I touch the screen (Lenovo ThinkVision M14t, which identifies as a Wacom-compliant touchscreen). Is there any fix for this that I can try?

[Daniel van Vugt (vanvugt)]

It appears this crash stopped happening in Ubuntu 20.10 and later, but there doesn't seem to be any record of *what* fixed it.

Certainly the ThinkVision M14t works for me - I've been using it in 22.04 and 22.10.
