(Firefox :: Downloads Panel, defect, P3)

Description

Attachment: screenshot 1.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

Download something and open the download manager or click on the download icon.

Actual results:

The icons are blurry.

Expected results:

The icons should be sharp.

I am using Linux / X11 with gui scaling set to 2x. Display resolution is 4K. The issue seems not to be a icon theme issue because I tested with multiple themes like adwaita.

The Bugbug bot thinks this bug should belong to the 'Firefox::Theme' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

On the theme side we don't have much control over these icons that are coming from the system, but maybe we can request higher-res pictures. Moving this over to Download Panel for further investigation.

We may be wanting to ask for an higher resolution icon to the moz-icon protocol here: https://searchfox.org/mozilla-central/rev/ece43b04e7baa4680dac46a06d5ad42b27b124f4/browser/components/downloads/DownloadsViewUI.sys.mjs#473,476,488 depending on the screen dpi

We should check if there's other code fetching these icons.
