[5.2.1f1] UI disappears if D3D9 standalone window is resized, or after first run

If you resize our standalone client window, the UI disappears. This also happens after the first time we run our client, until we rebuild it. This did not happen in 5.1.1f1. This does not happen in either editor, just the 5.2.1f1 standalone builds. Is there an API change that we need to be aware of, or is this just a showstopping bug that snuck through? The standalone client is a Windows 32-bit build, using D3D9, made with Unity Editor 64-bit 5.2.1f1

I have the same problem only on PC on MAC all seem to be fine..
Any workaround?

 

Is this fixed in 5.2.1p2? The issue tracker says it is fixed in 5.2.2:

The main issue fixed in 5.2.1p3, but there is a new bug reported in the comments when resizing:
