Have downloaded my Build here on Itchio again just to make sure the Files are OK.
Have absolutely zero Issues, I am unable to replicate your Issue.
So I am pretty sure the Issue lies in your PC-Build somewhere.
Driver Issue, Hardware Issue (i hope you are not on a Laptop).
Your PC-specs would be nice to know, because even my old Windows 7 Rig with a GTX 970 has zero Issues. 8GB DDR3 Ram and I7 3770 3,4 Ghz.
My second Windows 10 PC Rig with a RTX 2060 also has zero Issues. 16 GB DDR4 Ram and I7 9700k 4,7 Ghz.
