The result of git bisect is:

commit 5a06388bf83c97f49565ad482161645f996492c7

    Initial panel fitting changes

    Basic support for panel fitting.
    (cherry picked from commit 05cf07071e25f84dec3476a9bed7235ed50cd249)


But I wonder that in the bad cases the screen remained completely black
and did not react to any keystroke, so I had to restart the computer. I
could not reproduce the behaviour I originally reported while bisect...

Nonetheless I hope it helps...
