System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 436.30

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-08-05 19:34, hash: f41eb8b2a9
Worked: 2.83.4

Short description of error
Selecting the Z-Buffer as display channel for a rendered image causes an assert in a debug build of Blender. A release build doesn't display the Z-Buffer properly.

Exact steps for others to reproduce the error

Create a debug build of Blender
Render an image
Select the Z-Buffer in the display channel drop-down in the image editor

Triggered BLI_assert(!"Incompatible format passed to immDrawPixels");

Triggered `BLI_assert(!"Incompatible format passed to immDrawPixels");`

I can confirm that it works fine with the changes to the Image Editor.
