Hello
I have set groupy option "automatically group identical window together" as on.
Now whenever i am opening second instance of a particular file (PDF, WORD, EXCEL, etc), there is a strange visual seen on the top left of that application (not getting such visual if I have kept that groupy option as off)

Also, the problem is I cannot see the second file. I have to minimize that application and then again maximize it, so that the visual goes away and then I can see the second file. After that, it doesn't happen while opening 3rd or further any number of those files.
Another problem linked or not, I am not sure but groupy option of "only group if the window has been held for above (1/3, 2/3 or 1 second) is not working.
Window version latest 1903'
Groupy Version - 1.2
Thanks
