Snap Area problems in Sequoia

Bugs or Unexpected Behavior
1

Note:
Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS Console.app from the "User Diagnostic Reports" section.

I'm running the latest BetterSnapTool available from the App Store (1.9.12).

Describe the bug
A clear and concise description of what the bug is. Any bug reports that contain insults against me or my software will be deleted without warning (unfortunately this has become necessary to mention here).

My work computer was force-upgraded to Sequoia last night (15.0.1). I use my Apple M1 Pro MacBook Pro laptop with an external display connected over a DisplayLink docking station. I am running the 1.10.3 (Build 34) version of the DisplayLink drivers.

I have Snap Areas set up on my external display attached to my docking station. Prior to the upgrade to Sequoia, I have never had any issues. After the upgrade, when I drag my windows on the external display with Snap Areas configured using my Apple Magic Mouse, the Snap Areas flicker and sometimes disappear when I try to drag my mouse pointer over them to initiate window snapping. When I stop dragging, rather than disappear immediately as they would normally do, the Snap Areas linger on the screen for four or five seconds, still flickering. I am sometimes able to get my mouse pointer to land on a Snap Area while dragging, and if so, the window resizes as normal. But at the moment, Snap Areas are no longer functional for me with my Apple Magic Mouse.

When using the built-in trackpad, Snap Areas work as normal.

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

Following some additional experimentation: I am also experiencing this issue with an RF mouse.

The problem seems to be somewhat related to the speed at which I drag the windows. If I drag them slowly, there is no flickering of the Snap Areas and I'm able to land the mouse pointer on the Snap Area drop zones. If I drag quickly, I get the flickering.

Speed of drag is not an issue with the built-in track pad. I am only having issues with external mouse devices (both Bluetooth and RF). I hope this information helps.

When the flickering is taking place, BetterSnapTool is taking up 170-180% CPU. Right now I am watching a bunch of flickering of the Snap Areas taking place. It's been going on for over a minute, and I'm not even dragging any windows. When I mouse over the menu bar icon to close out BST to clear my screen of the flickering Snap Areas, I get a beachball.

Is there any way I can instrument the process or export some kind of log file to help diagnose the issue?
