Area(s) with issue?

File Explorer: Thumbnail preview

Steps to reproduce

There seems to be a memory leak in the File Explorer .svg thumbnail preview plugin.

✔️ Expected Behavior

The File Explorer .svg thumbnail preview handler shouldn't fill up all ram on the machine.

❌ Actual Behavior

Placing the attached https://openclipart.org/download/289287/ht28.svg file in a folder open in Explorer with medium or larger icon view causes a WebView2 process to chew up ram until it completely fills all available ram.

The .svg file came from: https://openclipart.org/detail/289287/houndstooth-15

Other Software

Windows 11 24H2 (OS Build 26120.3281)

It looks like GitHub tries to render the attached SVG, and causes the issue. Might be a good idea to remove it and just put the link, made it hard to reply to this 😅

From an Edge/WebView2 perspective - That's quite the SVG. It seems like it hangs Edge, Chrome, and Firefox on Windows. Safari on iOS doesn't event attempt to render it.

Given this repros on Chrome, can you open a Chromium bug at https://crbug.com? If you do that and link it here that'd be helpful for getting routed to the right team.

I'll leave it to PowerToys folks to make the call on if PowerToys should handle this type of leak/hang differently.
