Hi Max,

Could you try to see if version 4.18.0-2 of the Debian Linux kernel
works?  You can install it from snapshot.debian.org.

I have seen some reports of 4.18.0-3 being broken or causing issues with
graphics in certain circumstances (#916510, #916134, #914967) which may
be related to your issue.

Thanks,
