Graphics issues in Minecraft Bedrock on Android

Dear Support Team,
I'm using the Bedrock version of Minecraft on my Android 9 smartphone. Graphical glitches occur when I enter a world: Elements like leaves or sugar cane are displayed as flickering or are barely recognizable.
I've already tried the following steps, unfortunately without success:
- Restarting the device
- Reinstalling the app
- Adjusting the graphics settings
I would be grateful if you could help me resolve this issue. Are there any known compatibility issues with Android 9 or other settings I should check?
