*Steps to reproduce:*
# Create a new project.
# Right-click Hierarchy > 3D Object > Tree.
# Select Tree to view in inspector.
# Click on the branch group in the tree graph.
# In the Tree component, choose "Move Branch", "Rotate Branch" or "Free Hand" and use any of the tools.

*Actual results:* Lines in the same shape of the tree branch with choppy black backgrounds flash and disappear in various editor windows, sometimes multiple at once.

*Expected results:* This doesn't happen.

*Reproducible with versions:*
* 6000.0.21f1, 2022.3.47f1, 2021.3.44f1, 2021.3.26f1

*Not reproducible with versions:* 2021.2.0a1, 2021.2.0b1, **2021.3.25f1 (See notes)*

*Can't test with versions:* 

*Tested on (OS):* MacOS Sonoma 14.6.1

*Notes:*
* There seem to have been continuous but different issues with branch tools affecting UI since somewhere in the 2021.2. beta versions, but the +"Regressed from" is when the big line and choppy black backgrounds started appearing.+
If any of the following problems need more extensive testing, please contact ticket reporter:
** * {*}2021.3.25f1{*}, 2021.2.19f1 - the flashing is a much smaller box at the top left of the inspector, and a tiny line is visible in the corner of that.
** 2021.2.0b16 - scene view flashes and a tiny line is visible in the top of the inspector, no black box.
* Using Metal and Silicon editor.
* Lines are sometimes yellow, sometimes pink, not sure why.
