Broken: version: 2.82 (sub 6), branch: master, commit date: 2020-01-03 05:28, hash: rBeb6ca6cf9f28
Short description of error
When you switch from one of the transform tools (Move/Rotate/Scale/Transform) back to another tool, say the lasso select.
This enables the Gizmo manipulators, but if you didn't have any objects selected when you switched to the move tool, it won't draw the manipulators when you switch back.
Unless you disable and then re-enable them
Exact steps for others to reproduce the error
-enable Object gizmos (any)
-then deselect all objects (or have no objects selected at step 1)
-switch to the move tool, for example
-select an object
-switch to the lasso select
the manipulators will not display until you disable and re-enable them.
