Disappearing objects, Screen not updating properly
Over the past few weeks I've been noticing that sheet objects on the screen disappear randomly while using the application. Once it starts happening it doesn't stop. Sometimes if I click where I know the object is supposed to be it will reappear or flash, but as you can imagine this renders the application unusable. I am only seeing the issue while using Qlikview Desktop for Windows.
In addition to objects disappearing, in some instances, they will just turn completely gray. There is no pattern to this behavior that I have noticed. It just seems like there's some graphical glitch and the screen is not redrawing properly. Is anyone else experiencing this problem?
Example: This is what the screen should look like:
This is what randomly happens when the glitch kicks in:
I had just upgraded to 11.2 about a month ago (curiously right around the time this started happening...), but in an effort to correct this I just rolled back to 11.0. Unfortunately, I'm still experiencing the problem. I cannot remember if I upgraded from 11.0 -> 11.2 or from 10 -> 11.2. I guess I'll try rolling back to version 10....
I actually come across this problem a lot, and it only happens in Desktop (so it's only a problem for me while developing, since once it's out on the server it doesn't happen anymore). In order to "fix" the issue, I just turn Webview on and off, and everything goes back to normal (at least for a little while).
Go to the layout tab and check the selections you made in the Layer section. My guess is that the light blue Text Object that should be in the background has the same setting as the one that is disappearing. Try setting the blue background object to 'Bottom' and all of the actual objects with data to 'Top'.
I've done the same thing for a temporary fix, but there must be a reason this is happening?! I'm supposed to be demoing a dashboard for my Board and wanted to do it on Desktop to save from having noticeable lag in the charts... But not only is it making it impossible to author the dashboard in the first place, I certainly cannot have stuff disappearing when I do my live demo... in 2 days!!!!!
I've investigated this a little and the layering orders are set the way I'd like them to be. The stuff that disappears are often objects that have no ordering conflicts at all like a button or list box directly on the sheet background. I'm really at a loss here...
