MSTSC: Black Areas on Remote Desktop

Solution 1:

I solved this issue by disabling Persistent bitmap caching in mstsc options for my VM:

After doing this, I haven't been experiencing any issues for several month.

Solution 2:

For me, disabling 'Persistent bitmap caching' as recommended here worked. However, this reduces performance.

Instead, deleting the contents of C:\Users\\AppData\Local\Microsoft\Terminal Server Client\Cache and connecting again worked. This way I was able to keep 'Persistent bitmap caching' turned on, but not have any black boxes.

Solution 3:

There seems to be a problem with the auto detection of the connection quality. I had this sometimes in my environment.

I solved in mstsc.exe with setting under Experience the Detect connection quality automatically to a plausible value.
