sony vegas pro 12 render issue

[StutterBomb]

Hello! So i have spent good chunk of my day developing a new outro for my channel in Sony Vegas Pro 12. Every now and then I would pre-render it and notice some frustrating spastic glitches in the video. When i did a full render those spastic glitches where still there. I looked on the internet to see if other people had this problem and came across a post that had similar problems as me. Someone suggested disabling GPU acceleration since, apparently Vegas pro 12 doesn't support newer graphics cards very well. So i did that, rendered again and still got those graphical glitches. Now im stumped and cant figure out why vegas wont render my outro properly. Can someone please help? thanks!
