Seems OK on Linux 2.80 beta daily hash
26d5a3625ePlease attach a .blend showing the problem and mention your graphics card and driver
@StephenSwaney
Not sure a .blend will do much good. It's only like 3 or 4 steps and the only thing a .blend would do is have
import bpyin text editor.Here's a video.
https:*www.youtube.com/watch?v=SKWttHNXFZ4&feature=youtu.be
a) a .blend is always nice in case you have some weird settings
b) from your original screenshot, the 'duplicates' look like drawing artifacts
c) please mention your video card and driver
This isn't drawing artifacts. Look at the screenshot again, the outliner shows 10 duplicates and mesh data shows 161. It got duplicated 161 times. You can also watch the mesh data number changing in the video.

This seems like an error in the undo system, first guess would be it's related to the new unified stack so assigning to @campbellbarton.

Hm, interesting :)
I can confirm this. For me this can already be achieved by just typing in the text editor (could be "foo", "bar" whatever doesnt need to be valid python). Dont even have to
Run Script.Havent looked at the code, seems like undo/redo queue is somewhat intermangled/garbled. (you can also observe the text getting shorter - as if an undo in the text editor was performed...)
Since this is undo/redo related, I would like to ask @ideasman42 to have a look...
oops, guess I had this browser tab open and did not notice this was triaged already, sorry for the noise...

Changed status from 'Open' to: 'Resolved'
This seems to be fixed in master, cannot reproduce anymore...
(first thought blender/blender-addons#66172 was a duplicate I could merge, but fortunately this very report here seems to be resolved...)
(@AFWS: feel free to comment again/reopen if issues persist...)
