XenDesktop 7.6和GRID会话被冻结

我们遇到了NVIDIA GRID和XenDesktop 7.6的问题。
我们在XenServer和vSphere 6.0上运行vGPU，两者都存在问题。
在一天中间歇性地，用户XenDesktop会话似乎被冻结。
唯一的问题是虚拟桌面很好。
如果用户断开连接然后重新连接，他们会从中断的地方继续。
恢复会话的另一种方法是将Citrix 4.2接收器窗口调整为窗口模式，并立即恢复会话。
我们已经开通了Citrix案例并联系了我们的NVIDIA代表，但似乎没有人能解决这个问题，尽管无数公司遇到了同样的问题。
如果我们在没有NVIDIA显卡的情况下运行XenDesktop 7.6，问题就会消失。
有几个论坛帖子建议启用旧版图形模式并禁用桌面组合重定向来解决此问题。
对我们来说，这是一个解决方案而不是修复。
在此问题得到解决之前，我们无法转向生产。
这里有没有人经历过并克服这个障碍？
如果NVIDIA和Citrix能够共同解决此问题并为正确配置创建Runbook或安装指南，那将是一件好事。

We are experiencing an issue with NVIDIA GRID and XenDesktop 7.6.  We are running vGPU on both XenServer and vSphere 6.0 and the issue occurs on both.  Intermittently throughout the day, users XenDesktop sessions appear to be frozen.  The only issue is that the virtual desktop is fine.  If the user disconnects then reconnects they pick up where they left off.  Another way to get the session back is to resize the Citrix 4.2 receiver window to windowed mode and instantly the session comes back to life.

We have opened Citrix cases and contacted our NVIDIA reps, but nobody seems to have a fix for this yet although countless companies are experiencing the same issues.  If we run XenDesktop 7.6 without the NVIDIA cards the issue goes away.  There are several forum posts out there suggesting enabling legacy graphics mode and disabling desktop composition redirection to fix this.  For us this is a work around and not a fix.

We cannot move to production until this issue is resolved.  Has anyone here experienced and overcome this hurdle?  It would be nice if NVIDIA and Citrix could work together to resolve this issue and create a runbook or install guide for the proper configuration.
