Display driver stopped responding and has recovered on RemoteFX VM

Hi, I'm experiencing problems with RemoteFx VM's "Display driver stopped responding and has recovered". I found KB2519946. 

I have installed this hotfix on vm's and host server then I updated video driver on host server to latest one. The problem "Display driver stopped responding and has recovered" is still persist.

In client eventlog I see following warnings: ID 4101 Source Display.

Most errors  I see while browsing internet with IE. If I choose to use software rendering in IE I don't see this error but as I understand I don't use RemoteFX in this situation.

In host server event log I see following warning:

Event ID: 4

Source: RemoteDesktopServices-RemoteFX-Manager

Using CPU to compress because of insufficient GPU resources. [VM Name: vmName, VM ID: 9, Status Code: 2360303622]

Fix from KB2523676 is also installed. Steps from KB2501816 are already done.
