Selected Objects Get Filled With Orange Color (Mac)

When selecting actors in the scene they get filled with an orange color rather than the typical orange outline.

This is unrelated to the setting "Selection Highlight Intensity" as the bug will still occur regardless of this setting.

This seems to only happen on the Intel Iris 6100 GPU

[Edit]

User reported that it happens on their Intel Iris Pro 6200

1. Open a blank project
2. Select an actor in the scene

To verify please fix install the latest Beta OS by requesting access to disk image located at: [Link Removed]
Install instructions
1. On an external drive you intend to install the beta OS to, erase a partition in a HFS+ format (MacOS Extended, Journaled) or (MacOS Extended, Journaled, Encrypted)
2. Run the installer found by mounting the .dmg.
3. Run this installer as you would for any macOS, but select your HFS+ partition from (step 1).
4. Respond to the prompts as needed.
This distribution does not have an XCode to match. The latest version of XCode 9 (9A235) will install on this operating system, but there are some known compatability issues on NV configurations that may effect your GPU frame captures.

RESULT
The asset will be filled with an orange color

EXPECTED
The asset has an orange/yellow outline
