Hello, this is not the first time I encounter this problem. I've already created post with same problem being pointed out on Windows 10 which was successfully fixed by dev which can be found here https://forums.stardock.com/521832/page/1/#3898848. Now it's haunting me in Windows 11. I think it was confirmed that Groupy 2 paints additional separation line for some reason which is really distracting. If this line has some practical/debug function, please let the users decide whether it is should be painted or not. If this is not intended, please fix this issue for Windows 11 too. Now I'm gonna attach some screenshots of what do I mean by this bug (Also with screenshots of Windows 10 VM machine where this problem is fixed) and also winver and Groupy 2 information. Thanks in advance.
