Using 'Defer Panel Updates' and updating chart causes graphical issues

Hi,

Using 'Defer Panel Updates' to speed-up the updating of the front panel is sometimes very handy, and when developing GUIs I use it alot.

Recently I saw a very strange behavior, using a chart, which we confirmed to be related to the above mentioned VI-property.

Try out the example below and try switching the 'Defer Panel Updates'-switch a couple of times and you'll be seeing strange graphical issues in that chart!

This bug was found using LV8.2.1, but NI told me it also existed in LV8.5.
