m53 and m55 are also not fine.

how exactly are you judging "memory is very high"? is it growing unboundedly? or does it eventually stop, but you think it's using too much memory?

I open a simple page, and scroll it. the memory growing unboundedly and eventually crash.

Ok, so it's a leak.. does it happen in chrome too?
,

chrome is fine. I suspect texture memory is not free really in gpu driver using EGLImage between threads.

Yep, that's probably the first place to check

How do we usually find ways to avoid these bug aspects of GPU?
,

bisect if it's a regression. if it's not, try random things and make educated guess, or just talk to the gpu vendor
