black window when running heightmap example on Win 10 with Intel iGPU

[peci1]

Environment

• OS Version: Win 10
• Source or binary build? Source Ionic prerelease
• If this is a GUI or sensor rendering bug, describe your GPU and rendering system. Otherwise delete this section.
  • Rendering plugin: ogre (the example crashes with ogre2, but as that has limited win support, I don't consider it a problem)
    • Sensor rendering error.
    • GUI rendering error.
  • EGL headless mode:
    • Running in EGL headless mode
  • Generally, mention all circumstances that might affect rendering capabilities:
    • running on a dual GPU machine (integrated GPU + discrete GPU)
    • running on a multi-GPU machine (it has multiple discrete GPUs)
    • running on real hardware
    • running in virtual machine
    • running in Docker/Singularity
    • running remotely (e.g. via SSH)
    • running in a cloud
    • using VirtualGL, XVFB, Xdummy, XVNC or other indirect rendering utilities
    • GPU is concurrently used for other tasks
      • desktop acceleration
      • video decoding (i.e. a playing Youtube video)
      • video encoding
      • CUDA/ROCm computations (Tensorflow, Torch, Caffe running)
      • multiple simulators running at the same time
    • other...
  • Rendering system info: Intel HD Graphics 4600, driver 20.19.15.5166, DirectX 12
  • Please, attach the ogre.log or ogre2.log file from ~/.gz/rendering

Description

• Expected behavior: I can see heightmaps in the GL window.
• Actual behavior: I see only black frame.

Steps to reproduce

1. Just follow https://gazebosim.org/api/rendering/9/heightmap.html
2. Apply examples/heightmap: Fixed Windows build #1062 .
3. Build: mkdir build; cd build; cmake ..; cmake --build . --config Release
4. Run: .\Release\heightmap.exe ogre

Output

.\Release\heightmap.exe ogre
