MacOS floating Workflow bug

[bezthomas]

Mystery bug that causes a transparent workflow window to attach itself to the cursor in some areas of the screen.

Looks like you got into some sort of weird condition when dragging a tab. The ghost image should only appear when dragging a tab out into space and should go away when you release it (creating a new window) or move it back into the tabbed pane.

Can you reliably reproduce this, or is it random?

[bezthomas]

No known cause, so effectively random. It happened three times across two different MacOS machines. I agree it looks like the client thinks the tab is being dragged to a new location, but no tab dragging was involved- no button being held, just moving the mouse. Clicking off the client or along the tab bar to try and place the tab in a new (or the same) location had no effect, since the tab would only appear when the mouse cursor was on certain areas of the desktop. If I remember right, anywhere off the client showed the ghost tab. A few small areas of the client would show the ghost tab, but the client otherwise worked normally.

We can probably classify this as an intermittent windowing bug.
