Hello, Bug #850940 was fixed by xserver-xorg-core 2:1.19.1, but is currently not migrating to Stretch due to a block-udeb request by freeze. Is someone considering getting an exception for this migration?
I believe the "normal" severity level of #850940 is an understatement, as the bug drastically reduces the usability of KDE for people with rather common hardware. I am not subscribed to the list. Best, Gard Spreemann
