Dear Olly,

Many thanks for your work! I've applied your patch and found the program
working fine (including initial window size).

> I'm happy to NMU this change if you wish me to - just let me know.

Please proceed. I'll forward the relevant changes to upstream and
discuss the window-size problem.

Thanks again,
Christoph
