Oh dear. Well it seems I only thought I added code to only enable resize
support in multiwindow mode when requested, so it's always on for
multiwindow mode at the moment. That wouldn't be so bad, but it also seems
that the -resize code completely fails to correctly handle a change of
colour depth (e.g. from 32 bits to 16 bits or vice versa) leading to this
segfault.
Unfortunately, fixing this looks to be quite complex :-(
Thanks for testing, anyhow :-)
So... does that mean I have to roll back or face a seg fault after every
commute? Or is there a way to explicitly disable it?
I'm afraid so. As I say, I meant to add a means to disable -resize in
-multiwindow mode to avoid exactly this kind of situation.
Since it's the transition from 32bpp to 16bpp which breaks this, one possible
workaround would be to run your large monitor at 16bpp, which might also give
you working resize.
