This patch addresses two issues:
1- The lack of contrasts when the cursor hovers over the transform gizmo which is almost imperceptible.
2- Giving consistency among all the gizmos.
Before the patch when the cursor hovers over the the Interactive Navigation in the 3D Viewport or when it hovers over the Extrude operation or the Spin operation among others the gizmos always get highlighted with a white color, but the Transform gizmo (drag, rotate and scale) it doesn't follow this rule. Therefore, this patch solve the consistency between all of them.
Here is a video showing the before and after in action:
Thank you for your consideration.
