Guild Wars 2

Usually the graphic for the Flame Burst floor effect is fine, but sometimes, I get a discoloured square on the ground. I’ve only noticed it on snow, but can’t promise that it doesn’t happen elsewhere. Screenshot attached of an example from today.

I get this probably at least 7-10 times per day.

Edit: Lava Font, as Khisanth.2948 corrected.

Definitely not always on snow. Examples with different terrain, same spell.

That is Lava Font not Flame Burst. I get the same thing.
