Having this issue as well; have the HEIF/HEVC extension from the microsoft store installed. Images look correct in the default Photos app, but not Quicklook.

I have the same problem as above~ Apps install at Windows 10 2004, QuickLook Version: 3.6.9 (UWP), with HEIF extension.

Thanks @xupefei. That version works for me; heic files from an iPhone look normal. Only downside is that performance isn't great; it takes 3-4 seconds for the preview to load on a <2mb heic photo, versus the regular ~0.5 seconds for a 4mb jpg. I'm getting 20-35% CPU usage (on a 4c4t Intel i5 6500) versus 10% for the jpg. Same lag even if I reopen the same file over and over in quicklook. Though I don't think this is a new lag from the update; the old version has the same.

The loading speed is delayed for three reasons:

  1. Decoding HEIC images is much slower compared to JPG.
  2. The thumbnail component used by QL, exiv2, does not extract thumbnails from HEIC images. Therefore, you saw the loading icon until the full image is loaded. In contrast, when previewing a JPG, a thumbnail is loaded at first and the full image is being loaded in the background.
  3. The image decoder used by QL, Magick.NET, actually has a multi-threaded version (i.e., Magick.NET-Q8-OpenMP-x64), but only for 64bits OSs. QL still need to run on 32bit OSs so it still uses the single-threaded version.

It's time to abandon the 32bit OSs. Or add the 64bit branch.
