While I am sad you are having the same issue, I am also very happy to hear you are experiencing the same exact issue. It confirms 100% that it is not just me. The other person having the issue, was having 1 similar but not exactly the same.

Hello,

I have forwarded your report to the Stardock support team for their review and recommendations.

Please keep an eye on this thread for any updates.

We really do appreciate your feedback, thanks.

Yes, have tried turning all browser extensions off.... I don't have Punto Switcher either...

While the mouse I have is a gaming mouse, I got it purely for the shape/feel and don't use any of the extra software that came with it. It does have a DPI changing switch on the mouse but I don't have it set to crazy high (like most gamers) I just have it set to default settings. I had to actually open the software that came with it to check its settings. 

Polling Rate was at 1000 so I dropped it to 125 will test to see if it fixes issues, my DPI is at 2000 any slower and it will be too slow. 

I have tested with a few other mice including a standard dell mouse and issue still occurred. 

Issue still persists, even after reducing Polling Rate to 125, I then reduced DPI to 1200 temporarily (as it would be way to slow for work) and issue continued.

So far so good, but I know that as soon as I submit this it might start going wonky again. I use groupy tabs and switch tabs regularly like 100+ times a day... So the fact I was able to type this is a good sign.... Will know more though later... As this issue is so random....

I have the same/similar problem.  I click on a tab and the entire tab group sticks to my cursor and moves around the screen with my mouse until I click again.  None of the solutions I found here works.  Happens randomly several times a day.

We would like you (all with the issue) to try this build and see if you can still reproduce it:

https://cdn.stardock.us/support/uploads/Groupy_test05102021.exe

If the build does not help then I would want you to try adding the following registry key and rebooting:

HKEY_CURRENT_USER\SOFTWARE\Stardock\Groupy\Groupy.ini\Groupy\AllowFlicker = 1

You can use this batch file to auto add it if you do not feel comfortable doing it manually:

Let us know.

Preliminary tests (5 mins of switching tabs), good so far, but won't know for certain until I use it at work all day. As I have said before, it is so random, that its hard to catch purposefully . 

I can add a second confirmation about the new build.  No tabs sticking to my cursor today.

Just the install.

I did just the install.  No more tab sticking; but there is the very odd drag lag when dragging a group to another window. 

But by far better than the sticky tabs.

I have the drag behavior as well.  When I drag a tab group from one spot to another, the mouse goes where I want it then the tab group follows the same path just delayed about a second or two.  I have it set with the tab group bar above the window and the drag behavior only happens when dragging by the tab group bar not the actual windows bar.

I didn't really notice this until now because I normally keep my windows maximized on my monitors.
