Problem description
For phetsims/qa#816

When I take a screenshot in the Screenshot Wrapper, the velocity and gravity arrows are missing. Also seen in master, but nothing came up in the console.

**I tried version 1.5 and the screenshot was correct.

Steps to reproduce

1. Go to either screen in the Screenshot Wrapper
2. Check Gravity Force and Velocity checkboxes
3. Press Take Screenshot button

Seems like a sim-specific issue

I am also seeing this when I take a screenshot from the PhET menu in the standalone sim and the PhET brand sim.

This issue is also seen with iOS 15.5 using both the screenshot wrapper and the screenshot tool in the PhET menu.

Good catch, it's fixed in the commit and ready for review in the upcoming RC. We will also need to check that the fix doesn't negatively impact performance.

No performance problem were reported in the preceding dev tests. Closing.
