Same error here with a Creality K1 but along Y axis and no error along X axis (thanks for the hint by the way it helped me today as it appears the bug is only along one of the plane axis).

Same error with version 1.9.1, MacOS, with any printer and Y-axis mirror is broken also. ADD: error occurs only after usage of "Auto-orient", manual "Lay on face" seems to be ok

same Error after mirroring in Y in 2.1.0 beta Leiste seitlich.zip

[lennoxdk]

same error mirror and rotate

[BETLOG]

+1 lay on face (affects a 270 degree Y axis rotation) right click, clone, +1 move clone a few mm away from original in ~X axis mirror (clone), X axis dolly/pan/zoom view, deselect clone, or leave it selected... seems to make no diff slice (tab - which is extremely unreliable in linux BTW, pressing tab to slice may or may not happen ~50% of the time) app exits silently
