Stack group not centered

Issues
1

I have searched a lot but couldn't find this issue.

Phone : Moto G5 Plus

Android Version 7.0 (default display size)

Launcher :Nova launcher default setting.

I have created a widget containing 5 rectangle each same size in stack group(horizontal center) .

Height= $si(rheight)$

Width = $si(rwidth)/5$

Result widget left space at left side.

If i change display size(from android setting) widget looks fine.

What do you mean with "if i change display size from android settings" widget looks fine?

Pure android comes with option to change display size. Check screenshot.
