Got problem with my Nintendo Switch. When playing 3D games, graphic artifacts appear - part of the image (models, textures, polygons idk) flickers black. This happens both in the dock and in the portable. In two-dimensional games, this problem is not observed.
Unfortunately, there is no guarantee. Console is a year and a half old, did not drop, did not fall, did not fill with water. What could be the problem and can I do something about it? :<
Live in small city in Russia, so there is not so many services that could dyagnosis Switches.
Link to a video (sorry for that, but this problem hard to discribe):
