I can confirm this issue. I'm getting this undo problem in v1.0.0-beta2. In 
addition to opening documents for too long, the undo function won't work at all 
in very large images.

Today I run into this issue. I can reproduce it with a personal .ase file, I 
don't know if it's related to this specific issue, but I'm pretty close to fix 
it.

It could be related to cels with a position different than (x=0, y=0) (you can 
change the position of a cel pressing Ctrl+left mouse button).
