Thanks, however, in my exporter is exactly same problem as in yours, just
where your stops creating files, my creates just white background.
Interesting thing is that sometimes when it is unable to export, I save and
quit Pharo, reopen and it exports fine. I would say something about memory
related something, but when I opened 500 windows, it did not stop working
because of that.
Plus my exporting via morph seems to have another limitation, which is 10000
px on width and height, anything beyond it gets cropped.
Anyway, here it is, just updated with scaling down when too large, few fixes
(like exporting canvas which is not open anywhere):

Jan, I went through your exporter, and it seems to do
an interesting job.
I will be happy to include it in Roassal for others to have a look at it.
