Description David Elm 2013-03-18 05:05:28 UTC
The display position of the underbrace is above and to the left of the formula (what looks like a relative (0,0) position) instead of below and centered.  

The position of the overbrace is below and to the left.

The item used in the overbrace and underbrace is positioned correctly, it is just the brace that is badly positioned.

The pdf's generated a document with these, though, are fine.

This is a screen shot of both the underbrace and overbrace behaving badly.

I'm still seeing this problem.

It's a weird one.  I see it with both the installed version and the portable apps versions of LibreOffice Writer when I'm running on the Windows 8 OS.  But when I use the exact same portable apps version of LibreOffice on a Windows 7 machine, the problem isn't there.

It could just be I have a funny install of Windows 8...  I haven't had a chance to try it out on a different Windows 8 machine.

Screenshot (Linux) of example overbrace / underbrace formula with code

David, what is the Math code you are using to create the example shown in the attachment to comment#1 ? You can see in the attachment to this comment I am using:

{size +12 bold{3243}}
overbrace a over 31 newline
42 over {size +12 bold{4567}}
underbrace f

...which appears to display OK in v4.1.3.2 running under Crunchbang 11 linux. I will try and test this further today under MacOS 10.6.8 and Win7HP.
Comment 7 David Elm 2013-11-09 00:03:59 UTC
Something as simple as 

x underbrace 3

won't be rendered correctly.  When I export to PDF, it does just fine, though.  So I have a work-around.

BTW: I've tried the same thing out on a friend's Windows 8 machine and I get the same broken result.

Comment 9 foss 2014-06-27 21:06:17 UTC
David, can you please attach a test document so this can easily be reproduced.

Does this persist with LO 4.3RC1 on windows 8.1?
http://www.libreoffice.org/download/pre-releases/

if so please back to unconfirmed.
Comment 10 David Elm 2014-06-28 16:15:31 UTC
Something as simple as "5 underbrace 5" in the equation editor in Writer will not render correctly in Windows 8.1.  

I've just updated to 4.2.5.2 to double check, and the updates so far haven't addressed this yet.
Comment 11 David Elm 2014-06-28 16:30:53 UTC
Just checked the 4.3.0.1 prerelease version of LibreOffice and it has the same issue.
Comment 12 Beluga 2014-11-25 08:40:39 UTC
Back to UNCONFIRMED.
Comment 13 David Elm 2014-11-25 13:32:28 UTC
Still an issue on Windows 8 (but not Windows 7) as of LibreOffice 4.3.4.1.

Comment 14 Joel Madero 2014-12-30 17:15:08 UTC
This is probably the coolest bug I've seen in 3+ years...truly only affects Windows 8...so strange.

Tested on:
LibreOffice 4.3.5
Windows 8.1
Ubuntu 14.04
Windows 7

Bug ONLY appears on Windows 8

Marking as:
New
Normal - can prevent high quality/professional work
Low - while it's pretty inconvenient, it's affecting a single OS and only when using a particular feature that is not used by majority of users (formula, using specifically underbrace/overbrace)
Comment 15 Joel Madero 2014-12-30 17:45:54 UTC
Tested on 3.3 and it has the same issue. So this is inherited from OOo, updating version to reflect this.
