I quit out firefox and tried some games today, and I didn't experience the issue -- i think you might be right! What a weird thing, i had no idea there was a vram memory leak in Firefox. So crazy. Thanks for updating, i really appreciate it
Yea, I'll let you know if I figure anything out.
Restarting the game tends to work for me 1/2 of the time, I haven't had to restart my entire computer yet.
