From 5d993ac26c9aa87b1bd5783ccd261e7e7fcde26d Mon Sep 17 00:00:00 2001 From: Selim Cinek Date: Fri, 13 Aug 2021 15:03:06 +0200 Subject: [PATCH] Fixed an issue where the statusbar was made opaque even though it wasnt Because on Pixel 4 and other devices, the light reveal scrim doesn't have full alpha, the notification panel was marked opaque which removed the wallpaper. This could lead to the wallpaper not being visible in a couple of situations where it should have been, leaving AOD exposed. Because of a separate bug (b/196306312), whenever the wallpaper is hidden, we'd see a color layer, which would lead to the screen becoming flickery and awake on AOD.
