3d borders vanish

When I open VIs with large clusters (~200x5000 pixels), the 3D picture items vanish after few redraws. It disappears for all controls afterwards.

LabVIEW bug or display driver bug?

JP,

   Not sure exactly how to reproduce your environment. Are you saying a error cluster with the borders expanded exhibits these results? I tried dreating one (and error cluster) and expanding it to +200X+5000 (why do you need a cluster several screens wide?) and it hasn't exhibited the symptoms you described, it is just a REALLY big error cluster.

 

P.M.

The image is an error cluster (regular size to fit) as displayed after the symptom appears. The large cluster is not used for user display. It is a data structure of tens of parameters that I read/write from/to INI file and flatten to send to a device. The problem remains after I restart LabVIEW, but is corrected after a reboot.

JP,

I seem to recall seeing something like this once, about 1 - 1/2 years ago.  It was for an RF project where we stored various measurement data in a cluster before being processed.  A rather large cluster... well... relatively speaking, of course.  The cluster was created to keep the vi clean when running the wires. 

It occurred only once and I didn't pay attention to it.  It was on XP, with LV7.0.  It's too long ago now to recall any pertinent details.  I just thought it looked weird at the time.  What I do recall was the error cluster not having it's 3-D box.  I cannot recall any of the other boxed, though.  I do seem to recall that there was a large table which was displaying measurement data and displaying any out-of-bound measurements in RED.  It was part of an RF tuning process over a frequency range.  I don't remember seeing anything odd with that table..

Too long ago....  sorry.... 😐

However...  I seem to recall that the only thing on that particular Front Panel which was displayed was the table and the error in / error out boxes.  The rest was off the screen as not-pertinent to the operator to see. Which may explain why I would not have seen anything else.

Wish I could help you more, buddy!

The PC's were equipped with standard ATI graphic cards, nothing special and the "regular" versions from 2 years ago.  I doubt it is related to display..  Is it a bug??  Dunno.... Maybe the vi didn't have time to refresh the display...  πŸ˜‰  In our case, the table was displayed for a few seconds, only, while being filled-up with data...

So, you're saying that this behaviour is reproducible???  "Fascinating" - Spock
