floating window issues (updated)

Floating windows have a blank space at the bottom which says "no frame data available". See the screenshot attached "unity-floating-window-bug.png". It's been a while since I used the Windows/Mac versions, but I dont recall seeing that in those versions.

The window has the same issue after being docked, see the screenshot attached "unity-docked-window-bug.png"

I'm using Unity on Ubuntu 14.04 (I recently switched from Mint temporarily for the purposes of testing, though I see the same issue there). Using proprietary Nvidia 355.11 drivers, GTX760.

If I can furnish any additional info, please let me know.

Thanks,

Jon

That's the Profiler's message when you haven't recorded anything yet (haven't run the game).
