Confirmed regression between 0.106 and 0.107 (don't have U's to test). Looks like a bug here. Finally build older binaries for 0.106 and tested - Regression is 0.106u3.

MAME changed the video rendering system from 0.106u1 to 0.106u3 to a new one. And since this releases
the visible area in *all* vector games has been changed. The vector graphic bumped a little up so that
some gfx's in games like Eliminator and Zektor are out of the border. Check also the animated GIF's
and the Tempest overlayed/zoomed-in picture.

Believe me, the visible area in Sega G80 vector was wrong before 0.106u1 !!!

I have now corrected the visible area in the Sega G80 vector games for each game (see DIFF file). I started
every game in window mode, take screenshot with IrfanView and use a graphic program to check the border.
I used screenshots with scrolling/rotating text or objects flying in or out of the screen. The vector
graphics ranged now 1 Pixel from the border, which looks better in windows mode.

I looked at this patch to submit it for you this morning and it doesn't look right at all. Yeah, everything for the said games (and other games in the driver) are all on screen, but it looks like it's set up in a 16:10 style, not standard 4:3, complete with "black bars" at the top and bottom of the screen. In viewing pre-0.106 and the first viewable post-0.106 binary for these games as well as current (before your patch) and I do not see the same ratios being used at all and the whole screen is used, not some arbitrary view area. Therefore, the patch is rejected as submitted.
