I've just installed Lightroom Classic 11.0 (on Windows 10) and took a look at the new masks, but have found 2 strange behaviors. In both cases, the overlay for a mask that is not selected stays visible, although it shouldn't. Here's how to replicate:
Behavior 1:
- create 2 masks
- with Mask 1 selected, press and hold S to display the pins of all the masks
- while holding S, hover with the mouse over the Mask 2 pin to display the overlay
- with the overlay still visible (i.e. the cursor on the pin), stop pressing S
- the Mask 2 overlay stays visible, although it has not been selected.
- hovering the cursor on the pin of the (still selected) Mask 1 will temporarily hide Mask 2 overlay and show Mask 1 overlay, but when the cursor is moved away from the Mask 1 pin, the Mask 2 overlay reappears
Here's how it looks:

The active Mask 1 contains only the visible radial filter, while the overlay that is shown is from Mask 2, after following the steps explained above.
Behavior 2:
- with Mask 1 selected, hover the mouse over its pin. The overlay displays (correctly).
- with the cursor still above the Mask 1 pin, press and hold S and move the cursor over the Mask 2 pin
- Mask 2 overlay doesn't show (it should)
- release S and move the cursor. Mask 2 is now displayed, though Mask 1 is still selected
- as in the previous case, hovering the cursor on the (still selected) Mask 1 will temporarily hide Mask 2 overlay and show Mask 1 overlay, but when the cursor is moved away from the Mask 1 pin, the Mask 2 overlay reappears
In both situations, I can reset the overlay visibility to its correct state by either holding S and moving the mouse anywhere on the picture, or simply by moving the mouse to a side panel.
Regards,
Michael
