Temporary fix per project is by deleting not needed functions to meet word limit. ex: wave, jitter, etc. Was tested on a variety of devices from Android version 9 to latest

Juju Edit: Original post title also implied that a similar problem was encountered in Scribble Junior as well.

Released two games on Android with Netflix that uses Scribble 9 and ScribbleJr and this never came up.

What devices are you targeting? I see that you're compiling for a Mali 400 GPU.

The device ive tested it on was a duoduogo some off brand Android it's Version 9. Another was Sony Xperia 10 III, and a few others i forgot. Ive had other people test it, on different devices as well at least 2 had the issue. It works fine on my Samsung A21s.

Im building the game using VM, min sdk 21 max sdk 35.

Redact the ScribbleJr. I just notice you release an updated one il try that. The ScribbleJr i tried was which ever one was the latest with Scribble 9.0 beta

[JujuAdams]

Scribble Junior 1.5 has no shader changes compared to 1.4. Scribble Junior's shader is also miniscule compared to Scribble Deluxe so I doubt that the two issues are the same. Please report the bug for Scribble Junior separately (with debug logs) as the two technologies are radically different.

I'm not going to make substantial changes if problems affect "off brand" phones. There is massive device fragmentation in Android and no one has the time, least of all someone doing this for free in my spare time, to fix everything. The Mali 400 GPU, for example, was announced when I was still in secondary school. Android SDK 21 is a decade old.

Stuff like a Sony Xperia 10 III is more concerning since that's a recent release. I recommend recompiling under SDK 26 (which is the minimum that Netflix target, 7 years old) and seeing if that tidies things up.

"I'm not going to make substantial changes if problems affect "off brand" phones" I understand, and much appreciated. I just wanted to bring awareness, in case other's ran into it.

As for jr, when I think about it, i think I had Scribble imported when i tried ScribbleJr as well, so the issue may have been Scribble shader not Jr's. Cant recall as I've tried those back in August, and only just today re imported Scribble to try again with the update.

In any event I've gotten it to work by simply removing some methods i don't use from the shader itself, so i'm extremely happy with that.

[JujuAdams]

mmok. I'll leave this ticket open for future users.

If you can find the time to provide further logs it may be possible to narrow down the cause further. In the future I would like to write a system to automatically slice out unused methods which would solve this problem as well as improving performance.

[RicardoCarey]

Sorry for late response, but sure will in the coming days when free.

Thanks again. Appreciate your work.

I tested in a blank project with only 1 object 1 room.

None edited version: scribble_9_3_2_not_edited_logs.txt

Worked: Object's draw gui code draw_text_scribble(10, 10, "[c_red]Testing[/c]"); Failed: Object's draw gui code draw_text_scribble(10, 10, "[rainbow]Testing[/rainbow]");

The failed one only shows white rendered text.

Edited version: scribble_9_3_2_edited_logs.txt scribble_9_3_2_edited_shader.txt Removed wobble, jitter, pulse function, and it's calls to free up space(i just deleted stuff really). Both examples worked perfectly after.
