1719818 - When firefox loads a new page, there is a brief flash of white before the page loads. This can cause seizures depending on what the next page loads.

Status: RESOLVED DUPLICATE of bug 1740499

(Core :: Layout, defect)

Description

[kajiy81984]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:89.0) Gecko/20100101 Firefox/89.0

Steps to reproduce:

Click a link on a website

Actual results:

White screen flashes, followed by the next page loading (sometimes the flash then the loading can trigger seizures in a family member, so we're swapping back to chrome until this is fixed unfortunately)

Expected results:

No flash of a white screen, maybe just have it hang on the old page instead of flashing white while new page is processed

Hey Kaji,
I tried reproducing this on the latest versions of Firefox Nightly 91.0a1 (2021-07-11), beta 90.0 and release 89.0.2 but there is no flash.
