Raid frames completely non-functional (each frame displays ERROR and does not update on status changes), strange white coloring on unit frames, "pet target" frame is stuck on even without a pet active, settings window has a blinding white background and can not be moved. Only addons enabled are Z-Perl and Swatter. Errors linked below in pastebin.

Some screenshot examples from during our PTR raids:

Raid frames:

White on player frame (does not always do this for some reason):

The strange stuck "pet target" frame, which appears to have the health bar updated sometimes but I couldn't figure out what was changing it:

Target of target frame:

Settings window (warning: blinding white):

This is what the player frame looks like on a fresh character with all modules enabled and settings copied from the "main."

Doesn't look the same as on my "main."

It's gonna be fixed with the next release.
