[0.1.0-pre8-rc1] Flashes on spacebelts and platforms from crystals?

[dense plank]

From time to time I encounter a bug like this on the video, where a flashes occures on the space belts and platforms. It looks like the flashes are created from the shapez instances or the crystals reflect the light to the camera.

I've attached my savegame as well.

I have the same bug, same version of the game, the game is running on default steam launch options, here is my pc specs and shapez graphics settings. Also it doesnt go away after a restart of the game
