Description kyle.vivian7 2020-02-26 05:22:54 UTC
Description:
When I input the correct command 'vec{x}' I get a strange dotted circle over the x. The vector arrow shows up, but is displaced by the circle so it is up and to the right of where it should be. It almost looks like the arrow is superscript to the circle above the letter.

Steps to Reproduce:
1. Insert Formula object on Writer, Calc, or Impress
2. Type 'vec{x}'

Actual Results:
An 'x' was printed with a dotted circle above it with an arrow apparently superscript to that circle

Expected Results:
An 'x' should have been printed with an arrow above it.


Reproducible: Always

On Win10 with LO 6.3.4.2 (x64), I don't reproduce this.

Could you give a try at https://wiki.documentfoundation.org/QA/FirstSteps ?

Just to be sure, do you use LO 64 or 32 bits? Indeed, you put "6.3.4.2 (x64)" in description but x86 (IA32) in Hardware Field.

Same on debian x64.
It could be a x86 related bug ( have different implementations on basic typechars), but I know the starmath parser pretty well and don't see where cold be an error.
Could be a font error ( a composed surrogated error )?

Please, if possible tell me your win version and the fonts you're using on LO math.

My version LO is 6-4-6-2 (x64)and the last Windows10. I use Liberation Serif police for formulas.

I Guess you're using the stable version.

Downloaded it and opened it LO 7.0 on fedora 32. Also using liberation serif. The cache image of the equation was clearly wrong, but corrected itself after open/close the equation.

I did see some bugs like this, when I did change the opensymbol font for STIX two math (changing the LO code). It had the arrow over dots circle for vector arrow with nothing to be upon ( a composed surrogated error since the second char is missing ). However opensymbol is the font used for all math symbols and can not be changed, so that's why it's strange.

I know it can't be an error related withe settings, because the font name ( opensymbol ) is directly written inside the code. That makes it even more strange because if it was a general bug, I believe we would got a massive error report.

Marking it as NEW, but don't really know where the bug could be. I'm sorry I can-t help.

I can reproduce this bug in 7.2.0.4 when substituting OpenSymbol by STIX Two Math. When using OpenSymbol, this problem goes away.

It appears the bug is still there, at least on my system.

It also appears when using asana math, Cambria and crimson pro. But not with Libertinus math, though there is a problem with the arrow phasing down into the other parts.
