have you tried Singularity?

yes

tried singularity and cool viewer... both are the same as firestorm. And now the new official beta viewer is bugged too

must be something with my computer

have you tried doing a clean uninstall on all of them, deleting the program files too and starting all over?

its the only thing that worked for me when all my viewers got bugged last year

yes, i did that. And after that even the firestorm beta mesh got bad, which was good before. I might do it all over again

it soo sucks when they get funny, I hope it works this time

thank you Ashia, for trying!
