Oh no.. i had this bug some time ago with some systems... probably is a regression.. can you send me one of the images you are trying?
Also, would you please try to execute Laigter from console and see if any message appears when changing to preview?
Hey, i've tried in different machines with win10 and couldn't reproduce your problem.. could you give me your full system specs? What Opengl versions you support? The problem is with the installable version or with the portable version or both? have you tried in other win10 machines?
