Using the masking brush doesn't draw red in real time.

[John25546602elnt]

I have just changed my laptop to a lenovo yoga and re-downloaded my editing apps. In lightroom I now cannot see the masking brush filling in red areas in real time as I do it. It only shows the red areas I drew on after I release the mouse or stop drawing on the touchscreen. This was not the case in the past. I have tried all settings and can't seem to figure this out. Can anyone help?

This is in reference to the lightroom cloud based version and not classic.

I should have attempted this first, but I have Uninstalled and reinstalled the program. Now it is working as it should.
