Hello and welcome to the Minetest forums. Merry Christmas.

You've successfully summoned a rare demon kind of display artefacts.

Based on the bottom right "Activate Windows" text I assume it's a rather freshly set up computer. Please check for graphics driver updates (by Windows or on the manufacturer's website).

Merry Christmas too!

"Activate Windows"

this is because I'm using Windows 10 insider preview and I'm sure the graphic driver is most recent .

1) What's your Minetest version? 5.1.0 stable or 5.2.0-dev should both be fine.
2) Does the bug also occur on older builds, like 0.4.17.1?
3) Disable shaders. Optionally restart Minetest. Same problem?
4) Disable 3D-clouds using the Settings menu. Restart Minetest. Same problem?
5) Disable clouds entirely (setting enable_clouds = false). Restart Minetest. Are there still display artefacts?

For your information: F12 in-game creates a png screenshot.
