Minimal reproduction project (MRP)

I believe this isn't project dependent but just in case the project below should be dim.

It is probably this function. I'm not sure yet whether it will be activated before the splash screen.

I just tested on version 4.2.2, and the issue also exists there. Someone in the forum suggested changing to gl_compatibility, but it did not work for me. I wonder if there is a temporary workaround.

Can you also reproduce it if you override the splash screen? Use a different image file and display it for longer. For example 3000 ms, does the splash screen remain dark for 3 seconds?

Are you using the default splash screen in your project or a custom splash screen image? If using a custom splash screen image, make sure it's using the Lossless compression mode in the Import dock. Other compression modes may not work correctly.

@Alex2782 So I tried what you suggested, but I extended the duration to 10 seconds just to exaggerate the result. Apparently, the splash image only appears for a split second. When I slowed down the recording, it was visible only until the app became full screen. By the way, it’s also dim during the time it appeared.

I also discovered an inconsistency with the splash image size as well. However, since it has already been discussed here, I won’t delve into it any further.

@Calinou I tried both the default and custom splash images. Additionally, I ensured that their compression is lossless, but they still appear dim.

the splash image only appears for a split second.

@lazyvainglory is your input value 10 ms or 10000 ms?

10000 ms. = 10 sec.

I get what's happening now, based on the video output. The splash screen drawn by Godot is actually black all along. The image you're seeing for a split second when opening the app is Android's own placeholder image, which is a static image defined in the APK and not something drawn by Godot.

Thanks for the report! Consolidating in #74348, as this is the same issue.
