Bug: Objects move on a frame when copying

Still happening. And not just with frames. I have 4 frames (phones) identical in h/w side-by-side. At the top of the first, I have title on the left, a hamburger menu on the right, and a bit to the left of the menu, 3 icons. Whether I select all at once as individual items and paste in the other frames, or whether I frame the selection first and then copy and paste that frame in the 3 other frames (clicking the name on each first), the icons center themselves horizontally. Also, if I click on the selected items in the first phone frame and look at the position, x and y, it differs from the reported position in the other 3 frames by about 200 pixels (both x and y), despite being positiioned identically in all 4.
