Comment 2 stefano.d 2020-01-31 22:45:44 UTC

OK, I installed GNOME and I had this freeze also with GNOME.
Maybe it has something to do with the kernel or the NVIDIA driver.
If the BadWindow error is useless to you, you can close this ticket.

Comment 3 Christoph Feck 2020-02-04 00:29:29 UTC

Thanks for the update; changing status.

The BadWindow error messages are long plaguing us, but since they aren't annotated with source line information, it is nearly impossible to understand the cause for them. They don't seem to be harmful, either.
