Cheers! I had seen this one, but wasn't sure it applied to either KDE or the
nvidia card. 

Do you know any magic for tracing nvidia events? I gather it's not possible,
but thought I should ask.

You're not wrong about that :) I'll try to get something useful soon. 

At a first glance - keeping in mind I'm a noob at this on linux - I think I may
see a problem. 

I can clearly see by the plot, which monitor my mouse was on, by the
drm_vblank_event_deliveredN events on the corresponding monitor's row.

I can only assume by the name, these events should be spaced according to the
monitor's refresh rate; 16.67ms@60Hz/8.3ms@120Hz, for my two monitors. But what
I'm seeing is that every one of these events is spaced shorter than the maximum
refresh rate of the monitor - it's at 14.5ms and 6.4ms. Is it just me or is
that weird?
