raygui UI renders fine on android 16, but not on android 14

[oschonrock]

Working on a simple raylib game, which I am compiling for Desktop and android:

https://github.com/sebastian897/blockgame

The game compiles and runs fine on Android 14 and 16 and the android Studio Emulator. I am using

https://github.com/Bigfoot71/raymob
( I have symlinked the relevant files from the game repo above to a fork of raymob)

Then I added a simple menu showing two raygui buttons. It works fine on the emulator and via an APK on Android 16 (Pixel 7a).

On android 14 (Pixel 4a 5G) the buttons functionally work, but the rendering is broken:

There are weird "widely spaced gridlines" all over the screen, and when touching the button, the "pressed effect" shows up on large parts of screen outside the button, there is also some "flickering" in upper part of screen.

I am using the jungle theme. Not sure how to debug further.

@oschonrock I'm afraid I don't understand the issue, could you share some screenshot or video?

Thanks for response.

video of weird flickering and weird highlighting of area outside the button when pressed

screenshot on android 16, working as expected

The rest of the game (which does not use raygui) works fine on both phones.

This is the apk zipped up so github allows it.

app-debug.zip

Source code is as per above linked repo.
It's just the "menu screen", which contains just 2 buttons.

Wow... no idea... definitely it should be investigated but unfortunately no time at the moment to invest on this
