Unreal Launcher broken textures on OS X

My Epic Games Launcher shows some weird broken textures on any interactable element inside the Games Launcher.

The effect isn’t always the same. Sometimes it is subtle (second picture), but especially the login screen is really broken.

I’m using OS X 10.11.1, but the error also appeared with Yosemite. I have an Mac Pro (early 2009) with 2 2,26 GHz Xeons, 24 GB DDR3 RAM and a NVidia Geforce GTX 660 with 2GB of memory.

Hello,

Thank you for reaching out to the Epic support team. We have recently restructured our support system to better assist our users across Epic’s growing catalog of products.

Epic Games launcher support will now be handled by our Player Support team through an email ticketing system and active knowledge base. This support will encompass the download and installation of the launcher and the various Epic Games products hosted on the launcher (UE, UT, Shadow Complex, Fortnite, and Paragon). The launcher support team will also handle connection issues related to these products. The launcher support site can be accessed here (http://help.epicgames.com/).

Traditionally, Unreal Engine support has been handled through AnswerHub, and this particular process will not change. Users of the Unreal Engine may continue to post questions and issues as normal and interact with the engine support team. Any questions or issues that arise prior to the successful installation of the Unreal Engine should be directed at the website above and the launcher support team.

Those seeking assistance with the other individual products may do so through the following pages:

Unreal Tournament - http://help.unrealtournament.com/

Shadow Complex - http://shadowcomplexhelp.epicgames.com/

Fortnite - Coming soon

Paragon - http://paragonhelp.epicgames.com/

This answer is neither a solution nor helpful.

It’s not a solution, but it will be helpful when you follow the link to the new support page. I’m closing this as we won’t be continuing to provide Launcher support here on the UE4 Answerhub. Cheers.
