Black box is rendered at the bottom of the context menu

Reproduction steps:

1. Create a new project
2. Right-click the Hierarchy or the Project window

Expected result: The context menu is shown without any rendering issues

Actual result: The context menu is rendered with a black box below it

Platforms tested: Rocky 8.5, Ubuntu 22.04

Notes:

• Reproducible around 30% of the time
• On Ubuntu it is always reproducible
• On Ubuntu no black box is visible, but rather transparent one with black borders. As you move the mouse the transparent background flickers to black color.
