Yup there's yet another one @-zyik-!
This one's quite simple to make it happen

Steps:

1) grab any new canvas

2) doodle anything

3) duplicate the doodle layer as many times as possible

4) click undo until you see the layers covering each other

5) to make it even weirder, do everything 'til step 3, then merge everything, and then undo til the bug happens

Hope it helped :3
