I have a 2020 non-M1 MBP, latest OS. This is new behavior. I save an image from a website, either my dragging or right clicking, and it ends up looking like the I image provided. All white icon, "PNG." And yes, "Show icon preview" is always checked. The fix is to uncheck it, restart, then recheck. White jpeg then turns into the intended image. Went to the not-Genius Bar, the suggested re-doing the last OS update. I did this Friday, issue returned today. It's intermittent, and does not always do this.Just reset SMC and NVRAM for the heck of it. What causes this and what can I do? A complete re-wipe and reinstall of files from Time Machine? Or will Ventura install solve?

has anyone experienced this? Just dragged a run of the mill photo from Photos to desktop, and it shows like that. (above). Very intermittent, hasn't done it in a week.
 
Icon cache? Could be.

The important question:
Even though the icon may be "generic", does the file still open when you click/double click on it?
That's what counts.
 
Here's what I mean.
1) drag icon-----renders as generic.
-reboot-
2) drag icon-----renders normal.

Click to expand...
Open up Activity Monitor and search for a process called "com.apple.quicklook.ThumbnailsAgent. Force quit that process, and relaunch Finder (Option-right click Finder in your dock and pick Relaunch).
 
Is this a common thing? I did that once, and it came back. Once I install Ventura, can this happen again? So annoying.
 
Apple Twitter Support told me to boot up in Safe, then restart in normal mode. We'll see if that works. Otherwise, hope to fix this with Ventura.
 
....and this has come back AGAIN. two years later. different OS and computer. rrrrr.
