Tested versions

• Reproduces in v4.3.beta2.official [b75f048]
• Doesn't reproduce in v4.3.beta1.official [a4f2ea9]

System information

Arch Linux #1 SMP PREEMPT_DYNAMIC Wed, 12 Jun 2024 20:17:17 +0000 - Tty - GLES3 (Compatibility) - Mesa Intel(R) Graphics (ADL GT2) - 12th Gen Intel(R) Core(TM) i5-1235U (12 Threads)

Issue description

The default value for rendering/limits/global_shader_variables/buffer_size is 65536, which in compatibility renderer can produce the following warning:

MaterialStorage: Project setting "rendering/limits/global_shader_variables/buffer_size" exceeds maximum uniform buffer size of: 4096. Falling back on maximum buffer size.
  <C++ Source>   drivers/gles3/storage/material_storage.cpp:1115 @ MaterialStorage()

Whether the warning is issued or not seems to depend on hardware, it happens on my laptop but not on my desktop.

I'm not sure what should be changed here, the warning or the default, but I don't think a project with default settings should produce warnings.

Steps to reproduce

Create a new project and set renderer to Compatibility. Run the project.

Removing "Linux" from the issue description, doesn't seem to be OS related.
