InDesign 2021 16.3.2
macOS Mojave 10.14.6 (18G9323)
MacBook Pro (Retina, Mid 2012)
Intel Core i7, 2.7 GHz
16 GB RAM
Intel HD Graphics 4000 (1536 MB VRAM)
NVIDIA GeForce GT 650M (1 GB VRAM)
With "GPU Performance" enabled (or with "GPU Preview" on) images will not render if the containing frame has a fill applied. Note: InDesign reports that a compatible GPU and monitor are detected. Also, it doesn't matter whether "Animated zoom" is enabled or not. See screenshots 1–3.
With GPU Preview disabled (or with CPU Preview on) the images render correctly. See screenshots 4–5.
