Ok, here's what I found about my problem, you can try it yourself and see if it helps with your glitches.
I am running at 1920 x 1080 resolution. When I go to use the fader/knobs they jump erratically
top to bottom full right full left...
When I drop to anything in between 1920 x 1080 and 1600 x 900 the problem persists.
At 1600 x 900 or below all is well and everything works fine.
ALL my other DAW's (even 32 bit) have NO ISSUE with 1920 x 1080 resolution. THAT makes me believe
that this an X3 issue with the handling of higher resolutions.
