Description:
When hovering over relationship lines, I often see table positions being adjusted.

Don't know if that happens on other platforms, too.

How to repeat:
See above.

Thank you for the problem report. Please, check with newer version, 5.1.12. In case of the same problem, please, upload problematic .mwb and send the information from Help > System Info.

Still the same effect with 5.1.12. I changed the version BTW. Can't say if it is just a visual effect, but it's a little strange to the eye.

Hello Karsten,

I never saw this. Also not in huge diagrams.

When you hover over a relation then the relation itself plus the depending columns of the tables will get orange.

Could it be that you have this feeling because your tables are bigger and you usually see them in hinged position. And when you hover the table will expand to be able to mark the columns orange?

If I am wrong then I would need your mwb file and before/after screenshots.

I watched it some time. It seems to be a pure redrawing error. The redraw lags when scrolling, leaving artifacts on the drawing area. Some lines and tables don't appear where they're supposed to be (some pixels off, vertical and horizontal, depending on the scroll direction). However, the "internal" coords when moving the mouse cursor somewhere over the drawing area seem to be right so that the currently wrongly displayed lines and boxes get redrawn at the correct place and a jump effect occurrs.

It happens an a Lenovo T500 WinXP machine.

Tried with WB 5.1.12.

Ahhhh. You said the magical word "scrolling".

I was able to reproduce it with huge schemas where I scrolled a little bit around.

No reproducible in the latest WB Version
