Weird artifacts - compatibility issue?

Hello,
I get very weird and almost phycedaelic artifacts when loading the main weather page. Any ideas what can cause this or how to fix this?
Kind regards,

Hello, what browser are you using? I have never seen this.

Just a stock version of Firefox. It works fine on Firefox Android.

What version of Firefox do you have (latest os something older) and on which OS (Windows, Linux, Mac)?

Do you have the problem only with the temperature layer, or with all of them?

Windows 11, Firefox version 152.0.5 (64-bit). I just updated but also after update, the issued remained.

It happens on all layers, but the effect changes sometimes layer to layer. Also the values on hover/mouse seem... high.

(another weird thing I've noticed is that the image also uploads as one big green field when uploaded via Firefox, but not in Edge.)

Uploaded via Edge.

Yes, the values on hoover are read from the rendered image. So if image is incorrect, values are incorrect as well.

I have not fully understand the Edge mention. In Edge, does the problem occurs as well or you have used Edge only to upload image to this thread and website rendering in Edge is fine?

Are there any errors in Firefox Web Developper console (by default its under F12, but it can be opened from Firefox Tools menu).

Edge doesn't have any issue at all. The issues come in when uploading the screenshot, as well as when I try to view the radars.
I've also tried to run Firefox completely vanilla (no extensions, most relaxed privacy/security settings for tracking protections etc), this didn't fix the issue.

There a few errors;
