A white dot appeared on the screen with macOS 26

Note:
Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool

I did not do it.


Describe the bug
Since upgrading to macOS 26, one or more white dots have frequently appeared on the screen for no reason. I initially thought it was a macOS issue, but later discovered it was caused by BetterTouchTool. The white dots disappear as soon as I close or restart BetterTouchTool. This problem mainly occurs after the computer wakes from sleep, and while not always present, it happens frequently. It primarily occurs when I'm moving between home and the office, and often happens when I connect an external monitor and wake the computer.

I suspect that when the window is minimized or hidden, it doesn't completely disappear, leaving a few pixels behind.


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

could be some floating menu configured in BTT and set to 1px width/height

How can I fix it? Can I fix it by modifying the configuration, or do you need to modify the program?

you needtk check whether you have a floating menu configured in the floating menu section, if so you can delete it.

In any case this is definitely something in the configuration, we just need to figure out what

No, I did not set up a floating menu.
