STR:

1. Open Contacts app and open a new contact.
2. Scroll the page so that the "Comments" field is half on the screen and half off the screen.
3. Tap in the input field
4. The keyboard will open but a white panel will obscure some of the contacts app (see screenshot). You can see the white panel flicker.

This first started failing in the Monday nightly build but I am going to try and get a more accurate regression range.

Might be a tiling regression. Can we confirm this doesn't reproduce on 1.3?

Comment 2

[Tony Nguyen]

This issue doesn't reproduce on the latest Buri Master M-C build when APZ is disabled. When APZ is enabled, the white panel appeared 100% of the time following the STR from comment 0. I was not able to reproduce this issue using the latest Buri v1.3 build.
