Control: tags -1 + moreinfo Control: severity -1 normal I tried to reproduce this by installing a fresh jessie VM in virt-manager with debian-live-8.5.0-amd64-xfce-desktop.iso, installing gitk, then upgrading the VM to stretch in two parts (apt upgrade; apt full-upgrade), then rebooting. I did not observe a gitk display problem at any point during, between, or after these steps.
Do you have a detailed recipe for reliably reproducing this, ideally starting from a known state such as a live CD? Perhaps that is hard, but at least we can distinguish between a user configuration issue and a system configuration issue: can you reproduce on the same system under a freshly created account?
