Description Steven 2014-07-25 10:16:47 UTC
When playing an video using the glimagesink the output is flashing white frequently. This makes glimagesink unusable.
I tried different video files and codecs and the issue is the same.
I tried getting the latest nvidia drivers and the issues are the same.

This also happens on Linux btw, e.g. when you unpause or after seeking.

    glimagesink: keep the uploaded buffer around on successful redisplay
    We might need it later to perform a redisplay.  GstGLUpload will take
    of releasing the previous buffer when it receives a new buffer.

The fix for bug #736740 is needed here additionally to fix this one here in 1.4.
