When I am using the brush tool, my brush will stop tracking at the edge of the image I am trying to edit. If I back up the brush and its not touching the editing image it functions normally and smoothly. I can "force" it across the image by dragging across to the other side to where I think it has crossed the full width of the image and then the cursor will appear to jump from one side to the other and end up somewhere near where I dragged the moust. All editing functions work normally through sliders etc. Only the brush tool seems to be affected. Currently running mac OS v 12.0.1 and LRC 11.0.1. I am unable to use lightroom at the current time. This is repeatable and I have no identified work arounds. I am just using the standard Apple mouse when this occurs. I have also had issues with the intuos tablet doing the same thing. Please advise.
Golding, thanks for the quick reply. Based on your question I tested in full screen, partial screen, dragging to the full screen etc and there is no change. The brush when using masks hangs on the edge of the image. All other functions for lightroom seem to be normal. The mask selections work but not with a brush. I have had similar issues when using a WACOM tablet in photoshop. But this time I am just using the standard apple mouse and haven't seen this issue before.
