it used to be:

a linear layout (horizontal) with inner linear layout (vertical) Then there problem wasn't seen.

And it leads to a strange bug where the names are ellipsized starting a different text offset.

This cause that short names may be ellipsized and longer may not.

What can cause this?

does ellipsize have problems when layout_width="0dp" ?
