Intel HD Graphics issues with post processing

**Describe the bug**

While trying to run an OpenGL filament app on a laptop, I noticed I couldn't get the postprocess to work without MSAA 2x (pixels are rendered black in 1x).

By using the released samples, I could reproduce an issue that is probably related: disabling bloom breaks the rendering unless I enable the MSAA4X checkbox.

**To Reproduce**
Steps to reproduce the behavior:
- On a HD Graphics 520 gpu, run "material_sandbox -a opengl cube.obj"
- uncheck the "bloom" checkbox, notice the cube disappears
- check the MSAA4x checkbox, notice the cube reappears

The cube.obj file comes from https://github.com/google/filament/blob/main/assets/models/cube/cube.obj
