Sound Gargles in 3.5

I have been using Kdenlive for Audio/Video editing and in 3.0 it worked great. However, in 3.5 the sound gargles awful in the in-program playback. Did 3.5 do anything different with how sound it dealt with? And, if so, what should I do to get it back to the way it was. Otherwise, I am probably going to have to dual-boot with 3.0 to do video editing.

Also, separately, the new video driver in 3.5 is off compared with 3.0. In 3.0 I could run games like Hedgewars, on same bare level, and it worked graphic wise as far as not having the fallowing error. In 3.5, when I open the game, the entire monitor inverts all the colors into some psychedelic show. This is also caused by going from one place to another by holding ctrl, alt, F2. If I go back by using ctrl, alt, F7; I get this same strange color error that I do not get with 3.0. I tried deleting the new video radeon driver and swapping in the old by installing it from a .deb packing. The entire system then locks down and dies when I reboot into it.

Also, an a intel graphic system, Hedgewars sometimes has an odd thing where it will sometimes not boot another game after the first one or get very slow network play that it did not do under 3.0. Not sure if this is graphic driver related or something else. The graphic performance is almost shot under 3.5 where it worked fine, in playability respects, under 3.0. I could run full screen and 1024, 768. Now I am running in window and a low resolution to get choppy gameplay. What happened with the graphic driver in 3.5 that is causing such low performance compared with 3.0?

I pretty much either run on 3.0 or dual boot. I need 3.0 for gaming and video editing because the sound and graphic drivers on 3.5 are creating low and unsatisfactory performance on my systems compared to the performance of 3.0. I kind of assumed that updating would make them better, not worse, but I was wrong. Is there any easy way to run 3.5 and roll back the graphic and sound drivers so that my systems can function?

Otherwise, the new system is great. Thank GNU.
