  similar problem that I currently have, regardless if it has been
  closed or open.

  but it is a problem specific to the WebCord itself. I have tested
  if this bug occurs on Chromium/Chrome or any other Chromium-based
  browser that uses unpatched/upstream Chromium engine.

• I have tried running the build from the master branch and it does
  not have any fixes implemented according to my issue.

• My issue describes one of the unstable and/or not fully implemented
  features.

• I have found a workaround to mitigate or temporarily fix this issue
  in affected releases (please write it in Additional context section

Bug description

Pasting an image from outside of the application (i.e. a browser window or a screenshot tool) sometimes freezes WebCord to the point where restarting it is necessary.

Additional context

I'm using the Flatpak version of this application under Gnome (Wayland).
I have blocked the /typing endpoint, and all third-party websites except for the "GIF Providers" in the WebCord settings.
The only permission granted to Discord is Desktop capture.
I have also disabled hiding the window to the system tray, as Gnome doesn't come with a system tray.
I have encountered the same issue, under Gnome, with a different GPU (NVidia as opposed to an Intel TigerLake) and different CPU manufacturer (AMD as apposed to an Intel chip).

This might be due to the new mechanism I have implemented to actually make pasting images from the web functional. I guess it might be stuck at infinite loop where it does re-emit the event, but still finds it of wrong type.

And it is actually hard to trully fix the paste bug for me, I've just noticed some differences that occur for me to know whenever it has been fixed or not.

I guess I need to go back to remove HTML from clipboard, re-emit event, add HTML back method. Or find how HTML content changes in the clipboard to know why this bug occurs.

Alright, I see. I'm not entirely sure there's any HTML content in my clipboard.

It seems the issue has a higher probability of occurring if it's with a large image.

It should not freeze since commit b70c764, as WebCord will detect and prevent loops so event won't be re-emitted infinitely. However if it still does, I doubt I can do anything about it.
