Created attachment 56048 [details] math document causing the bug Problem description: Important: This bug concerns only the Linux version of LibreOffice. No problem with the Windows version. I try to open and edit this math document including grids created with Sinequanon software http://dl.free.fr/getfile.pl?file=/7xfy7rZr It's very slow to open, the PC freezes, mainly when scrolling, the cpu is near 100%. It's impossible to edit this document. When removing the grids, the bug disappears. Sinequanon software is here: http://patrice.rabiller.pagesperso-orange.fr/SineQuaNon/menusqn.htm System: Debian Squeeze and Wheezy My hardware: Core I7 Sandybridge 8Go Ram Graphic card: Nvidia Quadro 600, 1Go memory Steps to reproduce: 1. .... 2. .... 3. .... Current behavior: Expected behavior: Platform (if different from the browser): Browser: Mozilla/5.0 (X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0 Iceweasel/8.0
I described the bug there. It was reproduced by several people https://linuxfr.org/forums/linuxg%C3%A9n%C3%A9ral/posts/probleme-libreoffice-avec-les-maths
Reproduced with LOdev 3.5.0rc1 e40af8c-10029e3-615e522-88673a2-727f724 Ubuntu 10.04.3 x86 Linux 2.6.32-37-generic Russian UI
I think the problem is the anti-aliasing for the graphics, mainly the grids which are strangely made. To workaround: menu Tools > Options > LibreOffice > View > uncheck Use Anti-Aliasing (under Graphics Output). Tested with Version 4.0.0.0.beta1+ (Build ID: 789ec89fceb949eee482ecb7731a3d7b1ac0660) I do not have a MS-Windows version at hand to check if Anti-Aliasing for graphics output is enabled.

Nothing really changed: scrolling is smoother if antialiasing is disabled for graphics as stated in comment #3. Tested with LibreOffice 4.4.0.1.0+ built at home under Ubuntu 14.10. Best regards. JBF

Nothing really changed. If I am not wrong the grids are WMF images, that is a format which is not intended to be interoperable. Best regards. JBF
I guess it is a duplicate of bug 45820. Best regards. JBF

No problem anymore with LO 5.4 and current master. I tried with and without OpenGL enabled. @Madeiros: please could you try again with your current LO version? Best regards. JBF
This is no longer occurring, it is working in Libreoffice 6.3.2. If you are still having issues, please let us know.
