Everytime I enable this setting called "VBOs", sometimes I crash when a specific thing happens in chat. The only reason I enable VBOs is because if I don't have them enabled, I get low fps but with VBOs I get around 50 fps. I'm planning on getting a new computer soon so I don't have to enable VBOs and I won't have this problem but for now, It's getting quite annoying. Also, if needed, heres a picture of what I get when I crash.
