Hi, I found a regression in Flash Player v24.0.0.138 beta x64.

The video control bar (play/pause, volume, fullscreen, ...) is missing at

..., if I move the mouse over the video.

Flash Player v23.0.0.205 x64 is working.

Tested with:

Windows 10 Build 14955 x64

Firefox Nightly v52 x64 (NPAPI)

Opera Dev v42 x64 (PPAPI)

Google Chrome Final v54 x64 (PPAPI)

Also add version 24 (currently 10.3 till 23.0) to bugbase.adobe.com please.
