There is an issue where clicking and holding on any window title bar without moving the pointer causes Cubase to stop refreshing for a brief moment.
The issue can be reproduced very easily with the following steps :
- Open a project
- Press Play
- Click and hold on top of Cubase main window without moving the pointer.
Result : Cubase entire GUI stops refreshing for half a second.
This can be done with any window from within Cubase, that can be a plugin, mixconsole, audio editor, setting window, just to mention a few.
This is only true for “standard” windows that have a title bar.
Cubase custom windows like the F12 performance meters or the quantize panel cannot bring on the issue, but they will get frozen when the issue happens.
