Created attachment 75699 [details] Draw formula I'm using windows 8. I have a problem with symbol scaling in Math, a simple formula as "y=sqrt{ x} < x <= x^2 " is draw in erroneous way, the symbols are little respect the rest of formula. The symbol sqrt is draw with a break between √ and overbar, √ and ≤ are smaller than necessary. What could be the problem?
(LO 4.0.0.3 + Ubuntu 12.04.2) Confirmed. Especially at certain scaling levels, the √ symbol and overbar show noticable gap and/or vertical offset difference.
Hello Andrea, Did you try to play with menu spacing > Root spacing ? regards, Jacques Guilleron
Hello Jacques, Root Spacing in "format -> Spacing" is 0%. Not only symbol √ is small, also ≤ is smaller than <. If fonts are being used for symbols and √ ≤, it seems that these fonts are reduced. Whether it's a font problem?

Hello Andrea, I join an attachment to compare it with yours. I have defaut settings for fonts, so Times New Roman is for me the only font I use. You have Times also for variables, which font did you set for fonctions, operators? I explain those differences in rendering by changes in font settings. Is it true? Regards. Jacques Guilleron

Hello Jacques, I use Time in font settings, default. In win7 i have no problem. I attach an image for comparison, with the font settings. In the red circle you can see that the character is different. So I tried to change the font for the functions but there have been no changes. Regards, Andrea.
Hi Andrea, Just a quick test: In formula editor paste: y = sqrt {{x}over {sqrt {{x} over sqrt {x}}}} and give us a screenshot. Thanks Jacques Guilleron

Hello Jacques, attachment added. Andrea
Hello Andreaa, If you have installed no extension, no macro, no special use of character, I cannot explain why you have this mix of TimesNewRoman and Liberation fonts. Correct results with LO 4.0.0.3, LO 3.6 and LO 4.0.1 rc2 on Vista, LO 4.0.1 rc2 on Ubuntu 10.04 and LO 12.04. (qa-fr lists) If you get any change, let me know. regards. Jacques Guilleron
Jacques -- Here are my repro steps on Ubuntu 12.04.2 + LO 4.0.0.3: - Use original function "y=sqrt{ x} < x <= x^2" - Fonts set as follows: (TNR = Times New Roman) Variables: TNR, Italic Functions: TNR Numbers: TNR Text: TNR - Zoom at the following levels shows issues (gap between the root symbol and overbar, or the top of the root sign poking above the overbar): - 100% - 150% - 200% - 225% - gap - 275% - 300% - very close - 425% - close - 475% - 500% - 675% - small gap - 700% - noticeable gap - 800% - close --- Same type of problem noticed with the 2nd function, but different roots experiencing the issue at different zoom levels.
Hello Qubit, I think there is here two issues. One with the mix of TimesNewRoman and Liberation fonts that i cannot reproduce, and another with the link of root character and overbar. You writed an excellent report. Short, precise, and easily reproductible. I have no gap under Windows 7, but with Ubuntu perhaps you have it. On the other hand I see the poke above the overbar. So join a screenshot 700 % and report this separately. This will be a chance for an improvement. regards. Jacques Guilleron

Hello Jacques, I have the same problem with another windows 8 pc, libreoffice 4.0.0.3. Regards.
Hello Andrea, This is confirmed on qa-fr on several machines under Windows 8. So it would be only a Windows 8 bug for LO 4.0. I set it to normal, but not sure, what do do you think of? Regards. Jacques Guilleron
Hello Jacques, I think it is a high problem, I'm waiting to install windows 8 on my computer until this issue is solved. But i don't change the Importance because I'm not a developer... Regards. Andrea Antoniel
Hi Andrea, I'm not a developper. Here, I just try to help bug sorting. You have rights, like anybody, to change bug priority. Just write why. You have a flowchart at: https://wiki.documentfoundation.org/images/0/06/Prioritizing_Bugs_Flowchart.jpg that help. For me, this bug prevent users from making professional work, so it have to be set to Normal and perhaps Medium for second set because we cannot change this behavior. We have also to underline this is a Windows 8 special issue. But I don't know how. Regards. Jacques Guilleron
Hello Jacques, is interesting to me the flow chart, and comments to the bug are aligned with the flow. Okay. Regards. Andrea Antoniel
