Part of the page disappears as you scroll

[kevinfarrugia]

Description

When scrolling downwards on devices with a large viewport (1920 and upwards), as you scoll parts of the page get covered by a white area. This usually overlaps the requests table or the custom metrics if you have many.

Steps to reproduce

• Browser: Google Chrome
• OS: Ubuntu 22.04

Steps:

• Go to: https://www.webpagetest.org/result/221111_AiDc1Y_64P/1/details/#waterfall_view_step1 using a device with a large viewport (in my case 1920w)
• Scroll downards, notice how the table gets covered by a white area. (see attached video)

This could be a Chrome bug. What version of Chrome are you seeing this on?

#2519 is another Chrome/blending issue.
