I'll make sure this gets noted by the development team as a feature request. Makes perfect sense to me.
AND, I appreciate you helping out the community, who may very well run into this problem.
Are you trying to use "Application Timeline Trace" profile or "GPU: Performance Counters" profile feature of CodeXL?
I assume you are using "GPU: Performance Counters" run. Also, what kind of error messages are you getting?
Do you get a pop-up saying "Unable to gather profile data. This error can occur for one of several reasons: "?
Thanks in advance for your time and help.
