If you open a page with a large scrollable frame, such as a file in github, the top tile appears to be permanently low-res. If I turn of low-precision tiles, that section is just blank.  https://github.com/mozilla/firefox-ios/blob/master/Client/Application/AdjustIntegration.swift (select 'mobile view')
Assuming this is Nightly, I'm seeing this too. I think it might be a regression from bug 1259593 but I need to confirm that.
Version: 45 Branch → 48 Branch
Yeah, backing out bug 1259593 seems to fix it. I'm going to go ahead and do that.
