Thanks for filing this Diana. Does it reproduce on "normal" websites, (eg mozilla.org), or just about: pages? Could you attach your about support please - I'm specifically interested in whether the GPU is a Mali or an Adreno, because the Galaxy S9 has both variants.

Hi, for the GPU information, I did found on the about:support page in Device ID: Mali-G72. I did reproduce it on "mozilla.org" page.
