After returning to the app, the app briefly swiches to light theme

[pbocek]

Describe the bug
After returning to the app, the app briefly swiches to light theme. Seems to me like it happens everytime, after waking it from sleep. Doesn't happend if the app starts again.

To Reproduce
Steps to reproduce the behavior:

1. Open app
2. Go to desktop
3. Reopen the app
4. Wait few seconds

Expected behavior
I would expect, that it does not switch theme.

I have never seen this nor can I get this to reproduce

@gkasdorf or @sgriff96 either of you have any ideas?

This also happens for me when closing out of the image viewer sometimes.

It only happens when I set it to use light/dark according to your system setting.
Played around with it a bit and for me, it's resuming in the set dark theme, then after a second it's switching to whatever you've set as the light theme for a second before going back to the dark theme.
This happens pretty consistently on almost every resume of the app, like in 8/10 cases

This also happens to me, dark theme to light theme and then back to dark theme, or light theme to dark theme and then back to light theme.

Cannot reproduce. Using iOS 17 on iPhone 13. Latest app update 0.4 (2)

Seems to be a regression in .4. Only happens when the app restarts after iOS has unloaded it from ram, not just put briefly in background.

I assume it's some logic with the match system theme that's causing issues with this

[jderose9]

I’m guessing it’s related to the react native update. There’s a couple similar issues open on their repo, though they pre-date the current release. Still, maybe one of the workarounds described there could take care of it.

Getting same issue with latest 0.5 (3). Glitches to dark theme and back for me.

[gkasdorf]

Let's see if I can fix this.

[gkasdorf]

Fixed! Not sure how this ever worked correctly but anyway 🤷

[gkasdorf]

Ah, ok. There is an open issue with React Native about this like @jderose9 mentioned. facebook/react-native#35972

For now I've implemented a hack mentioned in that issue for this. Will re-visit at a later time.

This is still happening to me. Usually when I open the app, and it does seem to only be tied to the “match system theme” option.

It's fixed now, but Apple has not approved the updated build yet for the App Store. @TheFunkyMonk
