GUI interface slow since updating to 11 (from 10)

Hi, I’ve always been a very satisfied user of Toad. Since the shift to version 11 the GUI interface is so slow and sluggish that I literally can see the single objects being placed inside the screen when I switch views (editor, scheme objects, tables, views, etc.)

Does anyone else experience the same?

How can I improve this? Disable new fashion gui effects I dont need?

BTW: I’m on 11.5.1.2

Thanks.

Could you post Win version you use (full info).

Is slowing down only at first few minutes or constantly?
