Same issue on Sony Xperia One III. Anything in landscape is blank, grayed out. Fine in portrait.

Same issue on Pixel 6. Anything landscape is grey, portrait is fine.

QA, can you please verify that this bug is fixed in Fenix 109-111 with both the manual and automatic light/dark browser themes?

This Fenix bug sounds like Focus bug 1811549, which should be fixed in the next Focus update. I think that will be version 109.1.2. I know Focus 109.1.1 still has the bug.

When in Light or Dark themes the overlay is not there and the page displays properly. When in "follow device theme" the bug is still there.

Comment 7

[Chris Peterson [:cpeterson]]

Moving this bug to the top of backlog for investigation.

(In reply to firefox from comment #6)

When in Light or Dark themes the overlay is not there and the page displays properly. When in "follow device theme" the bug is still there.

Which Firefox and Android versions are you using? Do you also see this gray overlay in Firefox Focus or just regular Firefox?

I am using Firefox Focus 109.1.1 on a Pixel 6 running Android 13 and the bug exists only when using the "follow device theme" option.

Note, if I change to light or dark and then back to "follow device theme" Firefox Focus functions as expected for that session. If I swipe the app away and re-launch it in "follow device them" the bug returns.

Firefox Focus only, this does not exist in regular Firefox. Also version 109.1.1 on Sony Xperia 1 III. Identical behavior as described by Stefan.

[Chris Peterson [:cpeterson]]

Thanks for the details. Interesting that you both see this bug in Firefox Focus and not regular Firefox, while the original bug reporter saw the bug in regular Firefox.

I was not able to reproduce this bug on neither of the Fenix versions: Nightly 111.0a1 from 2/7, Beta 110.0b6, RC 109.2.0, with the following devices:

• Google Pixel 6 (Android 13),
• Samsung Galaxy Note 8 (Android 9),
• Google Pixel (Android 10), and
• Oppo Reno 6 (Android 12).

I was not able to reproduce this bug on Focus RC 109.2.0 neither. Tested with the same devices.

I was able to reproduce this today on the Focus RC 110.0 build 1 with Google Pixel 6 (Android 13).
The app was idle for some minutes, and after I opened it from the icon, the page was displayed with a grey layer. Tapping on the screen, dismissed that layer.
I have to mention that the device was set on dark mode, but Focus was set on the Light mode.
