--- Comment #35 from RealGecko alexandrbezenkov@gmail.com --- Sorry for late reply. I guess that's what was the cause of the issue, I used original .exe an it did not work, then I just replaced everything in PRG_ENG (including .exe) and it did work. Thing to note: I did not have texture doubling issue when I was running through Xephyr. I guess my setup is somehow different from yours. Maybe it's due to video driver? I use Nvidia 510.60.02.
