Flash Player loses hardware acceleration
The release of OS X Lion is causing problems with a host of Adobe software, a support article shows. "Known issues" of varying degrees exist with high-profile titles such as Acrobat, Dreamweaver, Illustrator, Lightroom, Photoshop and Premiere Pro. The biggest problems however lie with Flash, spanning apps like Flash Builder, Flash Catalyst and most notably Flash Player.
Whereas the latest versions of Builder and Catalyst may simply not work well in Lion, Player is experiencing higher CPU use in Lion due to hardware acceleration being disabled. Flash is already an infamously resource-intensive plugin, particularly on Macs, which have long had more trouble with the software than Windows PCs. Apple CEO Steve Jobs has in the past singled out Flash for causing stability and security issues.
Some other key Lion issues with Adobe software include the lack of Safari 5.1 compatibility for Reader and Acrobat plugins, and Droplets breaking in Photoshop CS3 through CS5. Adobe also points out that because Lion abandons Rosetta, any software from CS2 or earlier will no longer function.
Regarding taking advantage of the new features in Lion, such as Auto Save, Restore, Versions, Full Screen Mode and added gestures, the company says it is still undecided. "Since many of these features require new code in order to work properly, Adobe will investigate which ones make sense to our customers for inclusion in future versions of our products," it writes.

Adobe Remains Late to Need
Again why Flash and Apple OS community second class citizens.
