I still have issues with the drop target window as well as sizing problems. When resizing the group via a windows caption it works fine but resizing via the groupy dialog introduces lagged drawing.
The drop target window issue can be reproduced as follows. Make sure you are using one of the kbd modifiers (in my case I use shift +)
1. Press shift and then drag a window to the group. The drop target window will appear as well as a Faux tab showing the drop location.
2. Without releasing the mouse button release Shift (or whatever modifier you chose). Likely the faux tab will disappear but the drop target will not.
3. Move the ungrouped window around and it will sometimes dismiss the drop target window. If it does then a second attempt to group the window will not dismiss the drop target window after a successful grouping. You can see this by moving the group afterwards.
4. After step 3 some time later (usually a few seconds) the window is dismissed.
I noticed that while the window is still visible, a second grouping attempt (Pressing shift and grabbing another window) will dismiss it and then reposition it correctly for the new grouping attempt. I'm assuming there is but only one Drop target window.
I don't know what to say about the painting glitches with resizing as it works fine as long as the sizing comes from the apps window and not the groupy dialog. However it also works fine even from the groupy dialog with the "Integrated tabs" option turned on. It also on occurs on sizing that involve child window position changes. I.e. sizing the group on the left or top sides. Sizing from the right or bottom side does not.
Although nothing has changed in my specs I'll list them anyway.

If need be I can make another Video but I'm getting sick of ShareX. The videos come out jerky as hell and you can't choose just one monitor to record. The adrenalin software just doesn't record anything despite it showing the counter ticking away.
