Hot Corners and the Mission Control problem

[liwenfengg]

When I use the trigger angle to trigger the Mission Control in the upper right corner, a large old capture shortcut key will appear. However, if I use Control+arrow down to trigger the Mission Control, this bug will not appear.

My system version is macOS Sonoma of Version 14.3 Beta （23D5033f）. It should be noted that I have also reproduced this issue in previous versions.

If you need more additional information, please contact me. Thank you！

By the way, when I use shortcut keys to stop capturing, this problem will still occur and I need to kill the process...

This is an issue with how Mission Control decides what to display, as macOS uses a recent screenshot of the window to display in this animation. This is problematic for KeyCastr since most of the time the window isn't showing anything, but the OS will display a recent snapshot often with an unexpected transform. It has nothing to do with whether key casting is enabled or not -- so long as there was a recent display, it is possible mission control will show something like this.

There isn't an API to directly control what is displayed here, but tweaks to the window lifecycle may be able to improve it. I've also seen other apps having issues with unexpected transforming or displaying of unexpected results in Mission Control, so we're not alone here.

Okay, I get it. Thank you for your reply~
