I am running:
(base) [enricm@L0419006 ~]$ uname -a Linux L0419006.ka.surfsara.nl 5.3.11-200.fc30.x86_64 #1 SMP Tue Nov 12 19:25:25 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I am experiencing frequent input freezes when using TIlix. Mosty when connected to SSH, but I doubt this has anything to do as the network here is extremely good: This is the SURFsara HPC facilities in Amsterdam and I am some 200m from the actual supercomputer, cluster computers and servers. Latency si not an issue. The freezes do also not come back after a time.

I am inclined to think that this is something related to Wayland. I haven’t been able to find anything meaningful in the logs (journalctl | grep tilix).

Is there any way to debug this? OR any known issues in Tilix / Wayland ?

(I have opened a bug in the Tilix Gthub, BTW).
