Some features are super buggy on Intel iGPUs on macOS Sonoma

**Describe the bug**
We noticed a major regression on macOS Sonoma in our Filament implementation when using Intel iGPUs.

According to our tests, the bugs are exclusive to Sonoma. Earlier OSs do not have this issue.

Most of the artifacts are reproducable in `gltf-viewer`. Also, here's a video about the more interesting ones: https://youtu.be/3DD6_20G33k

_List of the artifacts we noticed:_

ImGui is artifacty.

TAA, FXAA, SSAO, SSR is artifacty.

DoF is also broken. DoF + TAA + Bloom combination results in a spectacular artifact.

If I turn OFF all post-processing sub-options, but leave post-processing ON, while setting MSAA 4x to OFF, I get a similar artifact. Turing post-processing OFF OR MSAA 4x ON removes the artifact.

_Other important findings_
* If I disable the buggy feature in `gltf-viewer`, sometimes I have to resize the window to remove the artifacts.
* Refractive shader with `refractionMode` set to `screenspace` is broken similarly. `cubemap` is ok.

**To Reproduce**
Try the aformentationed features in `gltf-viewer` on an Intel iGPU on macOS Sonoma.

**Expected behavior**
No artifact.

**Screenshots**
See above.
