I don't know what the CF code looks like to say, but if something broke (maybe when they went from 32 bit to 64 bit?), that sounds plausible. That's a good idea and should be pretty easy to test.

Several people here are claiming to see it regularly so it would be really helpful if they would record and upload it (to streamable.com or something).

It would make it much easier to tell whether it's real or not, and being able to see the timing would probably help a coder diagnose what's going wrong, especially if the player shows their triggers, gags and aliases directly after.

Something like Nvidia shadowplay or AMD ReLive would be useful for them if they don't want to use the diskspace to constantly record.
