Refresh issue

I have a presentation with numerous Web Page Widgets (22 in total) set to refresh every 5mins and a Calendar scrolling on the right. All widgets are coming from the same source.

I've had this presentation running beside me for almost 2 weeks with no issues, but now that I have the Pi mounted to the actual monitor, I am seeing refresh and stalling issues. The unit is connected via Ethernet (As it was in my office too). 

Randomly, certain widgets won't refresh properly and leave a blank white rectangle on the screen instead of the information that should be displayed.

I've restarted the presentation and restarted the player, but am continuing to see this issue randomly.

Any thoughts?

It was running on the Pi prior to this, just with a different monitor?  Does the new monitor use a higher resolution than the one prior?  A higher resolution does use more resources from the computer.

Did it do this right away at the new location, or did it take some time?  If it is the latter, could it be that the Pi is not in a properly ventilated location and is getting too hot?

Hey Neal,
Yes, it was on the Pi as well and the resolution is being set on the Pi side of things, so it's running the same. 

After install I didn't hang around for a long period of time, but I noticed as I walked by earlier today that a few of the items were not refreshing. I watched for about 2mins then asked somebody at the desk if it had been like that for awhile. That's when it refreshed again and everything was displaying properly, but before I could leave, a few more seemed to refresh incorrectly and displayed boxes again.

It should have enough ventilation, it's behind the TV right now, but it's at the top and there is lots of air-flow (That area actually gets colder because it's right by the doors, so it will keep it that much cooler too). Waiting on an order of double sided sticky tape to mount it to the back panel properly so it's not just hanging around back there.

Well the only other thing I can think of is the network environment.  I know that you've said its wired like it was in your office, but maybe there's a slower connection here causing a problem.  Congestion, etc.

My office is actually further away and using older Cat5 cables, the network cable was just run (Cat6) direct to the switch, which is roughly 80ft away (Opposed to the couple hundred from my office).

At least I'm not the only one confused by this! I will play around a bit more and see what I come up with...

Yup, I can't think of any other reason why it would act this way.  I did check to see if there's any part of the Pi that is scared of heights, but Google didn't come back with any valid responses. ;)
