Apache OpenOffice (AOO) Bugzilla – Issue 121708
Tokens, (like 'cdot') in Formula Editor are shifted
Last modified: 2020-01-19 06:21:23 UTC
Created attachment 80210 [details] Illustration of the shifted tokens. In the formula editor, the 'cdot' is shifted to the left, and the two parts of the sqrt are separated (see attachment) This first happened when I installed Windows 8, and seems to be specific to this OS.
I was able to replicate the two bugs shown in the example, also on a Windows 8 64-bit computer. I was able to reproduce this bug in 3.4.1 as well as version 4.0.0. I did not notice this bug occurring with any other symbols besides the "cdot" and "sqrt" symbols. I was unable to test this on a Windows 7 machine, so I have no insight into whether this is an OS-related bug or not. However, I would argue that this is a p5 level bug as it is only a minor issue and does not affect the functionality of the program, just makes it slightly more difficult to read.
I am replicating this bug with Niholas Moisan, but on a Windows 7 computer, running OOo-dev 3.5.0 AOO350m1 (9611) and OOo 4.0.1 AOO401m5 (9714). In both cases, when I try 25*13 (replace the * with the cdot) or 5*3, the dot is correctly centered between the numbers. Also the square root sign (root of 5) is correctly drawn. The dot and the square root on Moison's computer look identical to those in the "Illustration of the shifted tokens" file, but they look normal on mine. I am running with an Nvidia video graphics card, Lenovo W520 i7 computer Windows 7. Moison is running with a Lenovo ideaPad y410p with an NVidea GForce graphics card, also an i7. I don't know how to class this in terms of priority or severity for a broader market. I personally do a lot of mathematical writing (e.g. preparing slides for classes, writing textbooks). If the program had these problems on my computer, I would never use it.

Created attachment 82112 [details] Screen Shot of '-' and 'over' problem
This is still a bug under win8.1 64-bit: there are additional problems with the vertical placement of the '-' sign and a seemingly random allocation of a thicker and thinner 'over' line (the latter is not in a printout, so may be an aliasing issue on the screen). However, the displacement in to the left AND down does seem to affect most (all?) operators (see attached screenshot also for the ':' The document was started on Win7 and 4.00, and now migrated to a new machine - it was fine before so there must be a difference how Win8.1 handles fonts and distributes spaces... Can we have a fix please, because this makes working with equations really annoying
Please make sure, that the OpenSymbol font is installed on your new Win8.1 machine. The filename is opens___.ttf If the font is installed, please tell us the version of the font.
hello, I confirm that I wrote on issue 123312: installed on WIN 8.1 version is downloaded on your link. https://svn-master.apache.org/repos/asf/openoffice/trunk/main/extras/source/truetype/symbol/ opens___.ttf v 2.4.3 No change since the move to 8.1. cordially
Thanks for the download, but I had 2.4.3 already installed - so this cannot be the source of the trouble. To illustrate the problem again I attach three screen snips from the exactly the same file: 1) on Win 7 OO 4.0.0 Font 2.4.3 2) on Win 8.1 OO 4.0.1 Font 2.4.3 3) enlargement of 2) to show detail of Sqrt break, cdot and - positions shots are from two laptops, both i7 and geforce graphics, albeit of slightly different specs and at different screen resolutions (I tested that, it makes no difference to the effect)

Created attachment 82118 [details] Enlarged Win8.1 OO 4.0.1
I can confirm the bug with a freshly installed OO 4.0.1. (in fact, I had tried to switch to OO because the bug bothered me in LibreOffice). I think that this is also related to the problem that Greek letters are shown in some Sans-Serif font, which looks ugly. If I go to the selection of special symbols in OO Formula (where you can edit and define special characters) the selection menu says that they are from OpenSymbol, but the font that is actually used is, IMHO, a different one. I attach two screenshots.

Created attachment 82366 [details] Greek symbol not really defined with OpenSymbol font
I can see from the screenshot, that it is indeed not "OpenSymbol". Please take a text document in Writer and look, what the character table of the "Insert Special Character" dialog shows, when you select font "OpenSymbol". Please try whether a simple editor can select font "OpenSymbol". My guess is, that the font is not properly registered in Windows. You can try to delete the font OpenSymbol in Windows and reinstall it. Only to be sure, look whether a replacement is entered in Tools > Options > OpenOffice > Fonts. Which local has your Win 8.1.?
Opensymbol was, from what I could tell, properly installed but it was an old version (V1.10 from Sun, 2005). It looked the same in other applications. I now replaced it with a newer version, 2.4.3 from Oracle 2010. I am not sure whether this is the newest, but this is the newest I could find. There part of the problem is gone (the capital Greek letters now look reasonable and are no longer Sans-Serif) but the formatting shows all the problems that I had since I run it on Windows 8 (square-roots off, cdots shifted to the left, the divides-bar is much too short...). I attach a screen-shot of that. Interestingly, I got the best results when I completely uninstalled the open symbol font. There the Sans-Serif capital letters are back, but everything else looks fairly reasonable. I attach a screen shot of that as well. Thanks for your help!

(In reply to juffif from comment #18) > Created attachment 82373 [details] > Formula almost without problems, when no OpenSymbol is installed. Could you try to write a formula that includes integrals and partial differentials? I have the same problem since I work in Windows 8.1 with OO 4.0.1 and integrals really look awful. Have you tried to use built-in Export as pdf? Documents generated by that don't seem to be affected by this issue.

Well, I agree that it doesn't affect the functionality of the program, but I can't use OO Impress anymore since slides present formulas with a wrong aspect for a presentation. This bug is really annoying, specially when using integrals and partial derivatives.

Created attachment 82622 [details] Windows 7 Vs. Windws 8.1
I can reproduce the problems with integrals and partial derivatives posted by Mijail. I can also confirm that the problems are not visible in the PDF export, only on screen. This is also the case for the examples that I posted, withe sole exception of the square root, which has the (comparably minor) problem that there remains a small gap between the root sign and the overline. I also do not share the point of view that this does not affect the functionality of the program. I use OpenOffice mostly for slides, and I need to be able to project them in a way that looks professional.
Confirming these problems with Windows 10 And AOo 4.1.2 All my slides using formulas with cdot and sqrt look ugly
It is 2020. How can we get this problem fixed? Ugliness is very costly to OpenOffice's reputation. Thanks, Aik-Siong Koh
