I'm usually running emacs, firefox and pidgin at that time and often it
happens when I'm not using these applications at all. The wayland
compositor used is rootston contained in
https://packages.debian.org/experimental/libwlroots-examples
I'd be thankful for any pointers to track that down.
Cheers,
