I've made a trace of Dota 2 with apitrace, resulting in multiple performance warnings per frame looking like this when doing glretrace on the resulting file.

824941: glDebugOutputCallback: Medium severity API performance issue 4, Using a blit copy to avoid stalling on 12b glBufferSubData() to a busy buffer object.

824957: glDebugOutputCallback: Medium severity API performance issue 4, Using a blit copy to avoid stalling on 128b glBufferSubData() to a busy buffer object.

824958: glDebugOutputCallback: Medium severity API performance issue 4, Using a blit copy to avoid stalling on 12b glBufferSubData() to a busy buffer object.
