Description (last modified by )
I've had this reported by several users and can reproduce it myself as well.
When enabling the OpenGL Video Renderer playback appears to work fine, however upon starting playback a second time the screen remains black but audio is playing in the background. Restarting the frontend allows it to work again, but only once until another restart.
There is nothing logged to indicate a problem of any sort of problem during the first or subsequent startups however I did notice that the first playback outputs the OpenGL info (from inside OpenGLContext::Create()) but subsequent payback start do not show it as if the start of the debug variable is static accross startups

The main reason I set this to major is that I found that if I restarted and stopped playback several times after 3-4 attempts my X would segfault.

This issue is very likely to be similar to that of ticket #4526. Are you (or the users who reported) using a dual/quad core processor? I only get this problem when running the OpenGL renderer on a multi core processor machine (AMD64x2 4600 EE). The OpenGL renderer works fine on a single core machine (AMD 64 3500+).

I have this same problem on a AMD 64 3000+ single core machine.
oh my god I need to drink less caffeine
Hopefully that was understandable to someone other than just me :)
