Dragging tabs out often leaves floating "ghost tabs" in front of other windows
Since upgrading to Ventura, I have noticed a new appalling bug in Safari: very often, when I try to drag a tab off into a separate window, the drag fails but deposits a new floating tab, which I call a "ghost tab", in the foreground. This screen shot shows three ghost tabs floating in front of two Safari windows.
These ghost tabs cannot be selected or dragged. They appear to be in the foreground all the time. I can drag the remaining functional Safari windows around, but they stay behind the ghost tabs. The only temporary solution appears to be to quit and restart Safari.
This bug is in addition to the other one I noticed recently where I will drag a Safari tab to another monitor, and it leaves a blacked-out version of the original tab in the original window. The new copy is functional. This started happening in Monterey before my Ventura upgrade.
I'm using the current Ventura software as of November 4, 2022, on an M1 Max MacBook Pro, 64 GB RAM, 8 TB SSD. Would really appreciate a fix.
