Pepper Flash very slow

I’ve been using pepperflash for some time now in Leap and Tumbleweed. Just lately it’s started to run very slowly and jerkily so I reverted to flash.
I’ve seen some old comments about this online relating to its use in Chrome but this dates back about 3 years. I can’t find that there’s a fix anywhere.
Does anyone know anything about this?

I have problem in my opensuse Leap :‘(:’( not play my songs mp3
