Broken textures

Probably a renderdragon issue

Have you tried a full reinstall of the game?

Backup any data you don't want to lose, then try the following:

1. Backup your MinecraftWorlds folder (if you want to save your worlds) (Device storage > games > com.mojang > minecraftWorlds)

2. Uninstall Minecraft

3. Delete the com.mojang folder (Device storage > games > com.mojang)

4. Reinstall Minecraft

5. Run Minecraft and if it works restore your MinecraftWorlds folder

Sometimes a clean install of the game will help with these kind of issues.

Reinstalling the game didn’t fix the issue the problem with invisible interface and broken textures in world remained.

If possible, could you please include details about your system (RAM, CPU, GPU spec).
If you like you can run dxdiag and copy the relevant information from there. (Win+R → dxdiag) - be sure to remove any personal information, just the PC specs would be useful, along with the driver version information.

Pc model: HP laptop 15-bs0xx  BIOS: F.42 Processor: Intel(R) Pentium(R) CPU N3710 @ 1.60GHz (4 CPUs), ~1,6GHz Ram 4096MB Swap file: 6493 MB used, 7236 MB free Direct version: DirectX 12 Device: AMD Radeon (TM) R5 M330

Possibly a recurrence of MCPE-109870 or similar in nature.
MCPE-115421 also used AMD and is missing main menu

Thanks for the information and helpful comments. It looks like this may be the same issue as recorded at MCPE-109870.

In which case, this comment also provides a potential workaround for players using AMD hardware, which you might find useful.

I have this issue with main menu. I'm seeing only triangle shapes and not actual buttons. These shapes flashed and temporally damaged my screen, flashing left a shadow on my screen. Luckily it disappeared after couple hours.

Please check my issue (linked as duplicated) ticket MCPE-115421 which includes my AMD graphic card details such as drivers' versions. TLDR; Latest AMD Radeon Software version and drivers installed.

I have similar problem.  PC model: A960G+ BIOS:  Default System BIOS Processor: AMD Athlon(tm) II X2 250 Processor (2 CPUs) ~3.0GHz Ram: 3840MB Swap file: 4940 MB used, 4363 MB free Direct version: DirectX 12 Device: AMD Radeon R5 M240

Try using your CPU's integrated graphics. I had the same issue but once I change the graphics used by Minecraft it worked fine

Is this still an issue in 1.16.210.59?

I'd assume this is fixed given there haven't been a hundred reports of broken textures by now.
