Image of bug occurred on youtube and output from webkit://gpu

Hello everyone, i'm having some issues when i'm trying to use epiphany on my linux system, i already open an issue on them gitlab, but they tell me that this bug its from webkitGTK, so, here i'm...

Problem:

When i enter some heavy sites, like youtube or reddit, the performance drop alot and the screens start to blink in red,(sometimes stay red around 10s).

My system/ WebkitGTK info are on the attachment section, there you will encounter the output of "webkit://gpu".

i've already tried "WEBKIT_DISABLE_COMPOSITING_MODE=1", this only change the color of bug, from red to black and the performance drop as well.
