Square root symbol too small screen shot

Inserting formula object,

Insert>object>Formula

with

sqrt {%alpha}

will result in square root symbol being too small for alpha symbol, the square root should be bigger to fit alpha symbol.

Can be replicate in Libreoffice 7.0.0.0.alpha1+ (appimage) and 6.4.4.2 (official package in opensuse).

Root 'node spacing' is tight at 0%, but trivial to adjust in Formula editor's Format -> Spacing  -> 'Root spacing'; set to 10%

Verified there has been no recent change, to the 0% default Root spacing value--but think it could be increased to 10% to good effect.

Thanks, I just found out about the spacing option. The default should be 10% not 0%.

Well, we do have to be careful, 10% may be too large. The 0% spacing of this simple sm node of root and a single element is too small, but for a root of a compound node the 0% is fine, and 10% gets too large. So issue is internal to how the sm nodes are being calculated--probably needs additional logic there.

I think this can be close.
