Bug Some bugs with webgl and lightmapper.

Hello, I want to report some bugs.
The lightmapper always crashes everytime i bake, i tried enlighten, progressive cpu, progressive gpu, but they always had to freeze my pc at the point where i couldnt do anything.
Webgl has 2 bugs, The audio is all weird, it does some weird stuff, like if a certain sound plays, its all distorted, And the performance is cut by half, Normally in the editor my fps is at 60-145, But in webgl its always at 15-32.
Also webgl uses a lot of memory, Back then to me it wouldnt even work but it now works, But to my friend, he waits and waits and then it crashes saying theres not much of memory.
Any ideas on fixing this?

 

Any idea guys?
