Resolving blank/white screen issues

There are 3 main reasons for a blank/white screen being displayed in either the Paragon or Electron versions of the Symphony Desktop Application (SDA).

 

In SDA versions prior to 3.4.x and Paragon versions prior to 1.52, a caching issue may occur intermittently. This problem typically presents an error message similar to the following displayed in the Developer console (Figure 1):

To resolve this blank/white screen issue, refresh your SDA. If the caching issue persists, refer to the Knowledge Article found here about how to clear your cache.

 

If the issue persists after you have refreshed and/or cleared your cache, please contact the Symphony Support team at support@symphony.com and inform them that you are experiencing issues with a blank/white screen.

 

In SDA versions prior to 3.7.x, if the SDA was impacted by network connectivity issues on a computer, it would fail silently and produce a blank/white screen without any information.

 

This type of error now produces the following error message instead (Figure 2):

If the automatic reconnect does not resolve the issue, manually refresh your SDA to resolve this issue.

 

If the issue persists after you have refreshed, please contact the Symphony Support team at support@symphony.com and inform them that you are experiencing issues with a blank/white screen.

 

Finally, in some later versions of the SDA, launching the application displays a blank/white screen only (Figure 3):

To resolve this, open the Symphony.config file and update the disableGpu flag to true (Figure 4):

Once this has been done, exit Symphony, and relaunch the SDA.

 

If the issue persists after you have closed and reopened Symphony, please contact the Symphony Support team at support@symphony.com and inform them that you are experiencing issues with a blank/white screen.
