User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

  1. Open Youtube.

Actual results:

Sometimes, random user/channel icons are not rendered properly - instead of an icon, four dashes denoting a square are displayed. See the attached screenshot - the user icon in the top right corner and Gear Seekers channel icon on the lower left.

The affected icons are random and not tied to specific channels or users. Refreshing the page (F5) usually redraws the missing icons.

This problem does not reproduce reliably, and actually does not appear often.

Expected results:

Icons should be displayed correctly.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Is this still occurring?

It does sometimes. I think, last seen in version 103.

Next time this happens, please right click on a broken user icon and check for a "Reload image" option. If present, that means the image failed to load. If this is the case, we can move to the Networking component.

Here's a new instance of this problem - all icons for channels in the Youtube search results are rendered grey, and there is no option to reload the image. This is Firefox 103.0.1.

And here is the image that is saved using "Save Image As..." option in the context menu.

I think one way to reproduce this is to keep Firefox running while you suspend and resume the machine (in my case - laptop):

  1. Open Firefox and navigate to Youtube. See that user icons are rendered correctly.
  2. Suspend the PC (close laptop lid).
  3. After a while, resume the PC (open laptop lid).
  4. In the still opened Firefox, in a different tab navigate to Youtube again. (Alternatively, activate a previously opened but not yet loaded tab with Youtube.) Chances are you will see the issue reproduced.

I want to stress that this is one scenario that may lead to the problem, but is not the only one. Besides laptop, I have a stationary PC that I never suspend, and the problem also reproduced there, though a while ago.
