In MacOS you can hide the Menu Bar such that if the cursor is placed close to the top edge then the menu bar is exposed. This function is fundamental to the desktop functionality in MacOSX.
However, when running a full screen application to be used primarily with a touch screen it may be desirable to ensure the menu bar cannot be invoke via touch in which case you need to restrict the cursor moving close to the top most edge and we have introduced a setting to define the min Y co-ordinate posted by gestures.
To use this feature, set global setting "gesture mouse min y" to an integer value, e.g.:
upddutils nodevice set "gesture mouse min y" 4
A value of 4 should prevent UPDD Gestures from triggering the menu bar in a full screen app, provided that app is running on the primary monitor.
If it's running on a secondary monitor then the setting should be set to global Y coordinate of the top of that monitor plus 4. Note that the top of the primary monitor always has a Y coordinate of 0, hence the value of 4 will always work for it.
