Samsung updated the video drivers on the SGS6 which introduced a bug when disabling vsync. Both the driver versions are r5p0, but the md5sums of the blob differ. To work around the issue, make sure to never disable vsync by calling eglSwapInterval. We can't actually determine the driver version on Android yet. So until the driver version lands that displays the driver version string in the GL_VERSION string we will need to keep this workaround enabled at all times, which is a bit annoying. Current mali drivers return the video driver version in one of the EGL strings you can query. The issue with that is that Android eats all of those strings, so we can't query it.

// The correction of this bug is to check the boolean value against false which results in us

// not doing a negation of the source but instead checking against the boolean value we want.

|
// The issue with this is that Intel's Window driver is broken when checking if a boolean value is
