Steps to reproduce:

1. Open a Unity 2D Project
2. Open Physics 2D settings via Edit > Project Settings > Physics 2D
3. Navigate to the Layer Collision Matrix tab
4. Hover over one of the checkboxes. A tooltip should display
5. Move your mouse between the different checkboxes

Actual results: As the mouse moves over different checkboxes, some will display with a visual glitch, where one of two things could happen: 

• The tooltip displays the same size as the previous tooltip, and the rest of the tooltip is just a white or black square
• The tooltip displays the right size, but only the amount of text as was in the last tooltip displays, and the rest of the tooltip is a white or black square

When the visual glitch occurs, it will remain until the tooltip stops displaying.

Expected results: The next tooltip displays correctly

Reproducible with versions: 6000.1.0a8, 6000.0.31f1, 2023.2.0b8

Not reproducible with versions: 2023.2.0b7, 2022.3.53f1

Can’t test with versions: 2021.3.47f1 (doesn't support Ubuntu 24.04)

Tested on (OS): Ubuntu 24.04

Notes: 

• While the repro steps go through getting it to occur in the Physics 2D Settings Layer Collision Matrix, the issue does occur in all of the areas of the editor I have tested where there are items next to eachother that both have tooltips (e.g. Inspector, Sprite Editor)
