On Catalina GM, Snap Area outlines do not appear on secondary display

Describe the bug
On Catalina GM, on the secondary display, the snap area outlines do not display when moving an application into the snap area. The application still snaps as expected. Only the outline does not display.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

If applicable, add screenshots to help explain your problem. (You can just paste or drag them here)

Device information:

  • Type of Mac: iMac17,1
  • macOS version: 10.15 GM (19A582a)
  • BetterTouchTool version: 3.204 (1380)

This is a clean installation of both macOS 10.15 and BTT. The snap areas were created fresh (not imported).

Seems to work fine here, are you sure you didn't mark it as invisible in the snap area's appearance settings?

No, they are not invisible. The settings are identical to those on my primary display. On my primary, the outlines do show.
