Hello, I just updated to 8.0.10 and have been experiencing the same symptoms as @bzink1 .  
This is a vision app. My system resources are not noticeably higher.

Your issue was unrelated to the issue in the other thread, so I moved it into a new one.

Your issue is with the cell span dataset you’ve populated your power table with; you’ve got an invalid value entered in it somewhere:  
`java.lang.IllegalArgumentException: rowSpan must be a positive integer.`

For better or for worse, because Vision is running inside the same Java Swing application as the designer itself, a runtime exception in the paint event of one component can break painting updates for _all_ components. You need to fix the cell span dataset (or delete the component) and then relaunch the designer.

That fixed the problem. It was somewhat difficult to find the culprit and fix it with the designer not repainting. Thank you. @paul-griffith
