Firefox tabs turn all white

Since firefox 55 , every time when the Compositor (kwin) shutdown for fullscreen apps all the tabs in firefox turn white (can't see the page but can interact with it , like starting and stopping a video on youtube)
new tabs that are opened after that will work just fine until the Compositor is started or shutdown and than will also turn all white.

When downgrading to firefox 54 everything works just fine

Any idea why this is happening ? is this a firefox issue or a kwin issue ?

Hello!

Well, Firefox 55 included an expansion of the multi-process architecture. Can you go to about:support and check to see if “Multiprocess Windows” has a number greater than 0?

55 also included some more expansion of the WebExtension-based addon system. Are any of your addons incompatible with WebExtensions?

All the best,

-HG

In about:support the Multiprocess Windows is greater than 0 (1)
My addons being mostly just ublock , I think do not support the WebExtension-based addon system  but even with disabling it the problem still persist.
when I force the  Multiprocess Windows to be 0 everything work well...
Seems to be some weird issue with the Multiprocess Windows feature , it was working ok in 54 and 54 already had the Multiprocess Windows feature
