following the launch of the application from the RDS server, the desktop/screen behind the application window goes fully black. Generally, they are able to use Alt-Tab to move between windows.
Some users have reported that the black screen anomaly presents itself almost exactly 5 minutes after launching the application.
It has occurred on laptops/desktops running Win 7, Win 8 and Win 10. We are primarily a Win 7 environment, but in an effort to rule out the desktop OS and the PCs themselves, it has been tested on Win 8 and Win 10.
We were advised by Microsoft support to rename AcLayers.dll to AcLayers.old and the issue seems to go away temporarily but it changes the colors in the application window and that in itself becomes another issue with end users.
