Tiny Preview in Tab and notes symbols truncated

GIT commit: d61b0d1 / Windows7

1) Guitar tablature template
2) Right-click -> Staff Properties -> Advanced style properties

First result: tiny preview. And other behavior, maybe wished (?), the preview is not scrollable (4 measures on a single system instead of two systems, hence the tiny impression)

And other inconvenient: the Note symbols, ie the stems (after tick "Notes values" -> Note symbols) are truncated.

Worse in Tab French:

Previously display (two systems)

EDIT: I guess the "double" Tab display is related to another issue (?)
