18.104.22.16818 (13.12 WHQL) drivers, doing glPushDebugGroup() causes GL_INVALID_OPERATION.
Using a 6870 card for testing.
// Setup of the default active debug group: Filter everything in glDebugMessageControl(GL_DONT_CARE, GL_DONT_CARE, GL_DONT_CARE, 0, NULL, GL_TRUE); // Generate a debug marker debug output message glDebugMessageInsert( GL_DEBUG_SOURCE_APPLICATION, GL_DEBUG_TYPE_MARKER, 100, GL_DEBUG_SEVERITY_NOTIFICATION, -1, "Message 1"); // Push debug group 1 glPushDebugGroup( GL_DEBUG_SOURCE_APPLICATION, 1, -1, "Message 2");
returns GL_INVALID_OPERATION at the glPushDebugGroup() call.
There are no other openGL drivers to try that are newer than 22.214.171.12418 for vista 64bit. AMD don't seem to offer BETA drivers for 14.1 or 14.2 for Vista 64bit.
for errors, it lists:
GL_INVALID_VALUE is generated if length is negative and the number of characters in message, excluding the null-terminator, is not less than the value of GL_MAX_DEBUG_MESSAGE_LENGTH.
So, GL_INVALID_OPERATION isn't even listed as a possible error, so, this looks like a driver bug.
Yeah, I am sure it is the glPushDebugGroup() call that causes that error, I added glGetError() calls between and before all calls.
