SUMMARY Shift-dragging will change the brush size. This happens in-place; while the operation is ongoing, the mouse cursor does not move, it only changes in size. However, it appears that below the hood, the cursor is in fact moving, and stopping at the desktop border! The effect is that when resizing a brush, depending on where the action is performed, part of the value range is inaccessible. STEPS TO REPRODUCE 1. Create a new document 2. Set the brush size to 1000.00 px 3. Move the canvas so that it is close to the left desktop border 4. Shift-Drag left from close to the left border in order to reduce the brush size OBSERVED RESULT The brush gets a little smaller, but quickly stops resizing, even if you continue to drag left. EXPECTED RESULT The brush should continue to get smaller as you are dragging, until it reaches its minimum size. SOFTWARE/OS VERSIONS Windows: 10
