Bug: Slow or stuck file/image preview load time

[Jaluvshuskies]

Description

Haven't quite narrowed down what the issue could be, but when looking in some folders, the image previews aren't loading and are stuck with the grey preview. See image:

p.s. will add more detail to this when I can, it's late but I wanted to report this

Steps To Reproduce

1. Open files
2. Navigate to a folder with files that have previews (png/jpg/mp4)
3. Observe whether the file previews are shown
4. Set view type to small icons
5. Close files
6. Navigate to the same folder
7. Observe whether the file previews are shown

Steps to fix

Attempting to figure out what consistent fixes are, however I am unable to find a consistent solution

Here's what I've found so far:

• Zooming out a few clicks (from small icons to details) instantly fixed the issue once per session. It seem s to sometimes continue to fix when repeating this in the same session
• Doesn't appear to be drive related (SDD vs HDD)
• Unsure if related to file type (namely files with previews, like png, jpg, mp4)
• Happens with different folders, regardless of # of files in it (such as even just 1 image)

This is being caused by the WrapPanel template introduced in #10972

[gave92]

IIRC wrap panel does not support virtualization so it tries to render all items at once. Not sure if that's what causing this issue but if wrap panel gets reintroduced we need to check perfo on large folders.

I temporarily reverted the change because of the issue, the code is still there but commented out. I think we'll have to find a different way to wrap the text.
