I think I manage to reproduce it... But not all the time... 

Ok, so the steps I used to produce the bug. Better do it after a clean
X start.

1- launch platon this way : "platon LUSCOR.cif" [1]
2- on the right menu, Just under OptionMenus, clic on the third button.
Yes, the space between the ticks are buttons :)
3- You'll have a setwindowsize entry, make it smaller and the bug
appears in theory...

If the bug doesn't show up close it and do it again. Usually it shows
up on second time but I manage to get it the fisrt time as well... Don't
ask why...

One thing I am sure, when the bug is on and I change the window size
again, the bug usually disappear and I can't get it again unless I
restart X.

Hope it helps,
