Description:
Whenever I switch between the canvas and table editing area, the whole application within wobbles for a fraction of the section.

I'm providing a SWF from Camstudio with which I recorded the wobble I'm seeing.

It's nearly impossible to properly work with the application.

How to repeat:
Open a new ERR Diagram, create a table and edit it. The wobble effect is visible.

Recorded wobble of the application.

Attachment: bench_wobble.swf (application/x-shockwave-flash, text), 439.82 KiB.

It's maybe not clear enough from the SWF: I'm moving the mouse over each of the areas and doing a left click.

If you watch the SWF not in it's original size you may see artifacts from the mouse. They're only from the player and are *not* in the application itself.

Thank you for the bug report. Could you please provide your video hardware
specification and settings for record purposes since I am not able to repeat
on my side. Thanks in advance.

I'm on a Lenovo Z16p, 2GB RAM, Intel Core Duo 2GHz, with a ATI Mobility FireGL V5200 at 1920x1200x32, 115 DPI using an increased font size (Tahoma, 12).

Does this help or do you need more?

Thank you for the bug report. As work-around set less video resolution value.

Unfortunately changing the video resolution didn't change anything. I tried 1024x768 and 1280x800 (4:3 and 16:?), I also lowered the DPI to 96, but the wobbling was stil there.

I've the latest drivers for my card and, frankly, I haven't ever seen this before.

I've seen that problem in 120dpi, but in 96 it works ok. Did you restart Windows after 
reducing the dpi? If you did, could you upload another quick video of that?
(video is very very handy btw).

You absolutely got me on this one, I didn't restarted.

Defaulting to 96 DPI works without problems (after restart).

So, yes, this whole issue is about the DPI
