NI Settings owner for blocking call / assignment notes: please see video, not a regression (2.0 has different behavior so can not be considered 'unaffected')

NI No-Jun to see if this is a graphic issue.

[Blocking Requested - why for this release]: Blocking due to obvious rendering issue. cc'ing milan for his input.

I noticed that there are other pages in Settings that also repro this bug: Wi-Fi (first time only) Call settings Cellular & Data Bluetooth Homescreen Search Navigation Notifications Language Keyboards Firefox Accounts Find My Device Screen Lock App Permissions Browsing Privacy Media Storage (first time only) Application Storage Battery Accessibility Help

Triage: should belongs to core/graphics

Given the occurrence of the graphical issues in various pages per comment #6, easily reproducible, I am leaning on blocking this bug to get it fixed. We may have to end-up doing targeted testing depending on how risky the uplift is. I'll let graphics team comment on the risk or other comments here

Is this fixed in 2.2 with bug 1112332?

Need to verify with bug 1112332.

This might also be fixed with bug 1113435.

This does not reproduce in today's master, but in 2.1 and 2.2 it is still shown. Should the fixes be uplifted to 2.1 and 2.2?

Bug 1113435 is waiting for a 2.2 uplift

The symptoms described in this bug are a combination of two bugs. One is the culling bug 1113435 which is now fixed on master and will be uplifted to 2.2. This is responsible for the dark rectangle that shows up in the video. On 2.1 there's this: (In reply to Chris Kreinbring [:CKreinbring] from comment #2) > The bug repros on Flame 2.1 engineering with shallow flash. > Actual result: The section of the page containing the options will show > white as the page slides in, then the options will render. where the page shows white during the transition and then renders fully after the transition. This will be fixed by bug 1137203, which I expect to uplift all the way to 2.1. Since this bug is 2.1+, I'm going to dupe it to the latter as that will fix the issue seen on 2.1.
