X Y slipping skipping or other

in the love hate relationship with my vcore 500 a new problem occur:
i was trying to print the square tower of the pressure advance calibration protocol when i notice i was regularly shifting in diagonal.
i don't understand as i heard no noise from the motors, the grub screw are real tight and the belt tension seems fine ( can deflect to the point of touching the other when pinched, but don't flop ) i had done a frequency test: see pictures
and now i notice one of the belt is quite mangled and it as worked for like 1 h top... i have moved the gantry by hand before to feel any grab or anything and it was fine, i did checked because after initial install i had a belt slipping onto the edge of one of the guide bearing causing a bad grabbing so i re-did all the belt install . had it deformed the belt ? ( i heard that it was not so rare)
i wrote this post because i would like to found the cause of the problem so it doesn't show up latter.
i will had pic of the belt as i unbolt everything
