I have in writer the navigation toolbar (F5) and properties (F11) attached to the left and right side. (see screen shot) When I add a new formula, the formula toolbar is also on the left side. With 5.0.2.4 the navigation and properties tool bars are temporarily removed (OK). With 5.1.0.3 the navigation and properties tool bars are still and mixed with the formula toolbar. This causes many graphic artifacts and the formula editor becomes unusable (regression). (see other screen shot) This applies to impress, too. (not only in writer)
Created attachment 122457 [details] formula editor in 5.0.4.2 which is OK.
Created attachment 122458 [details] formula editor in 5.1.0.3 which is not OK.
Hi Dominik, I don't reproduce with LO 5.1.0.3 Build ID: 5e3e00a007d9b3b6efb6797a8b8e57b51ab1f737 CPU Threads: 2; OS Version: Windows 6.1; UI Render: default; Locale : fr-FR (fr_FR) & Windows 7 Home. Can you precise your OS? Thank you.
I have tested it on a Windows 7 laptop. And inside a virtual machine on my desktop; client and host are openSUSE 13.2 As well as on a second laptop with OpenSUSE Tumbleweed. (all 64-bit)
