Can't stop effect of C shortcut in Grease Pencil's draw mode Like the title says, I have created a new Grease Pencil Object (GPencil), went into the Draw Mode (upper left menu), than pressed C, but I can't exit from this feature (pressing ESC or anything else doesn't seem to help).

To be precise: pressing C in draw mode constrains the drawing into a circular/radial guide.

Possibly a bug?
Thanks

EDIT SOLUTION: Check the box in the upper viewport, with other guides checkboxes (Circular, Radial, Parallel...)
This is not a bug. In draw mode C activates the circular guide. You can click on the guides icon to deactivate.
