When changing the base point with the UI in a right to left language such as Hebrew, I have found that the base points seem to be horizontally flipped. So if I want to set the position of something relative to the top-left corner, I actually have to select the top-right corner as a base point.
I should add that this affects Draw and Impress
confirm this bug with master Version: 4.3.0.0.alpha0+ Build ID: a95b58060b01046a8881e97e0c5016e44200dd32
