Eternity and infinity related text oscillate brightnesses

[Phoenix51505]

Describe the bug
Eternity challenge, and eternity/crunch buttons (and possibly others) and text seem to pulse brightnesses occasionally, changing from bright, normal, and darker

To Reproduce
If applicable, steps to reproduce the behavior:

1. Look at the eternity or crunch buttons or eternity challenge menu.
2. Wait a few moments
3. Watch as they annoyingly change brightness every half minute.

Expected behavior
For the ui to stay static and not pulse
