I have problem with TightVNC 2.7.1 x64bit on Windows 2008 r2.
- debian box, kvm-qemu
- clean install Windows 2008 r2
- all updates include optional
- TightVNC 2.7.1
- DFMirage Driver 2.0.301
Before windows update everything was ok. After windows optional update I can no longer connect to the TightVNC server. From RealVNC Viewer I get error "RFB error: bad screen size 0x0". With TightVNC Viewer I get only toolbar from client, but without image.
It become independent of the two clean installed servers.
