Does clearing the thumbnail cache resolve this?

Does clearing the thumbnail cache resolve this?

No.

I can't repro this issue in Windows 11, is it only an issue in Windows 10?

Yes.

Does it also occur at higher scales? We might need to cap the requested size for the pinned items in Windows 10. Alternatively, we can make the black background transparent at runtime.

[hishitetsu]

Oddly enough, I found that this only occurs when the scale is 150%. It doesn't occur at 125% or 175%.

[yaira2]

That's interesting, perhaps they don't provide a size for 150% in which case we should skip to 175% on Windows 10.

I have same problem on 100% DPI

I have same problem on 100% DPI

That's likely unrelated, in most cases that's a Windows bug and can be resolved by clearing the thumbnail cache.

It occur to me when my DPI scaling is 100% or 125%.

[yrifl]

I don't have 150% dpi scale.
