Research direction

Start with Map/Extras.lua near line 741, where the reported stack trace shows CreateTexture, and trace the call from Map/WorldMap.lua near line 602 during TimeClose. Reproduce by opening and closing the map with only OpenMap enabled, then check whether textures continue to accumulate at the bottom-left pixel. Done when closing the map no longer leaves the visible dot or creates the reported pile of textures.

What happened?

After opening and closing the map, a small 1x1 frame that looks like 1 pixel gets placed right on the bottom left of the screen and remains there, and clears after a /reload only to appear again.

I spent a bit of time trying to see who the culprit was.

I tested it with only openmap, and the issue is there.

When the map closes, OpenMap creates ~440 textures on a single parentless 1x1 frame anchored at BOTTOMLEFT 0,0 (found with /fstack and Blizzard's table inspector). Each texture, as far as my findings go, and I used an LLM, so it might not be accurate, is white at about 1.2% opacity (alpha 3/255). They all stack on the same pixel, so together they add up to a visible dot. About 400 are created within one second.

Lua error (if any)
