Black Boxes of Terror
Recently, I’ve been noticing black boxes on the screens of my thin clients connected to VMware View desktops. These boxes will go away upon rebooting the thin client but come back some time later.
Here’s the fix. The black boxes are due to bitmap caching being turned on across your VDI or View session. If you’re using Microsoft Terminal Services (mstsc.exe), then you can turn this off. It’s a registry hack for VMware View users. So, here it is:
[HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Client\RDP Settings]
“BitmapPersistence”=”false”
“CachePersistenceActive”=”false”
I imported this into the registry on my thin clients (Windows XPe) and the black boxes went away.
Until Next Time
