Adobe and Linux

I have to test an application that uses Flash.
Updated to last Flash player from Adobe.
On their page http://get.adobe.com/flashplayer/ was a strange text:
"NOTE: Adobe Flash Player 11.2 will be the last version to target Linux as a supported platform. Adobe will continue to provide security backports to Flash Player 11.2 for Linux."

(Your system: Linux 32-bit, Firefox )


After update, I noticed the YouTube is played with interruptions.

eg:

Solution:
- DO NOT do upgrade on newer FlashPlayer if not necessarily

Cause:
- technical: on Linux, Adobe disabled Hardware Acceleration 
- Adobe passes the fault on others, when in fact they are unable to do a good software (fotomaniacu had problems with ACR on i7 with SSD):

"
The main reason for this move was:

  1. Security concerns.
  2. Unstable Nvidia/AMD/Intel and Open Source drivers - in combination with Adobe Flash Hardware-Acceleration.
Here the Link to the thread, where this has been discussed and confirmed: http://forums.adobe.com/thread/911321
Quote from the Link above:
"Unfortunately given the current landscape of graphics drivers and support for Linux based operating systems, we could not support Linux with Hardware Acceleration. Most drivers, including the ones provided from Intel/NVIDIA/AMD were too unstable to consistently work with the Flash Player. Sorry for the inconvienience." - Charbs09, Adobe Employee
"As of FP 11.0.1.152 there is no way to turn on HW Acceleration for Linux. We disabled it entirely facing security concerns, but we may re-enable an unsupported method in a future release." - Charbs09, Adobe Employee
