Thank you for the bug report. Are you able to provide the project model file (private if you wish)?. Try version 6.2.5 too. Thanks.

I have installed version 6.2.5 and problem remains. I attached the project model file. Good look.

Thank you for the feedback. Please check prior attached screenshot I assume your sample screenshot has as phantom table the produtos maybe is an environment issue you have or I am missed some important condition to make repeatable. My environment is:

Well, I am running my Win7 in a Virtual Box Machine. Do you think that is the issue? Well, anyway my workbench in Fedora 21 got working again, I mean, showing the table fields for editing. I guess I will give away from Win7, indeed.

On Windows 7 VirtualBox

Thank you for the feedback. Checked on Windows 7 VirtualBox machine (see attached screenshot).

What do you think my friend?

This is problem is caused by the large table figures. You either can make them smaller (not showing all columns then) or switch to software rendering. On Windows (and only there) Workbench uses OpenGL to render the diagrams. This imposes limitations on certain HW (integrated graphic boards) and VMs (max. texture size).

Using software rendering means to switch to cairo drawing, as used on the other platforms. This is not slower than OpenGL rendering, but doesn't have those limitations. To do so start workbench with the parameter "-force-sw-rendering".

This is a problem caused by graphics drivers in limited environments (especially VMs and RDP sessions). We cannot do anything about this and the only solution is to use software rendering (which is equally fast under these conditions). Otherwise WB runs just fine also with big figures/diagrams (tested on a 4K screen).
