Strange shadow/afterglow when moving sprites

Another strange problem in my game I don’t quite understand. It’s hard for me to explain this, but it’s visible:

Did you notice the strange afterglow when moving sprite/ moving camera over a sprite? It is visible on the side edge of the sprite. It is always as a “shadow” of the sprite that was in that position a dt before - so when moving sprites to the right on x axis it is always on the left edges of the sprite. There are many factors: pixelart scale sprites and upscaling it to the fullHD, render from orthographic camera, some post-effects regarding lights. But I can’t name the problem and what can I search to debug it.

Now I see, that this issue is happening only on my monitor (1920x1290, 59 Hz, 8-bit depth, RGB, color space SDR), but on laptop screen (120 Hz) it is not visible at all.

EDIT: And checked it in other projects - it is the same so it is regardless of rendering :confused:
