Remote App - poor performance due to high polling rate mice

clint furry 1 Reputation point

At my company we have been running into an issue as we transition to RemoteApp. Users that are running mice with polling rates over 250 experience sluggish response to all clicks and drop down menus. In some cases we also notice copying and pasting double pastes the same data or pastes sections out of order,

Using a cheap basic mouse is confirmed to fix the latency responsiveness for sure, and possibly the copy paste issue. But alternatively we are able to roll back the mstscax.dll, and mstsc.exe versions back to the server 2016 versions which also I can confirm fixes both issues.

The problem I have with the 2nd solution is that updates frequently update the mstsc.exe and mstscax.dll to newer version. And while I have been able to create a script that checks the versions and reverts as needed at time of user log in, it would be ideal if there were a permanent solution to this issue.

Any thoughts or recommendations appreciated.

    Hello @clint furry ,

    Thanks for your query.

    1.Is it working if you change the following group policy either locally or via GPO in an AD environment on all Terminal Servers/ Remote Session Hosts:
    Set the following to Disabled: Computer Configuration/Policies/Admin Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment: Use advanced RemoteFX graphics for RemoteApp – Disabled
    Ensure the Remote Desktop Client on server and client are the same 'Remote Desktop Protocol' version;
    Specifically, if you have a "high end" mouse, this will cause significant lag in RemoteApps. the "fix" is to downgrade your expensive mouse to a cheap one;
    The fix released for the right-clicking window z-order issue of Windows 10-
    RemoteAPP after windows 10 update 1803 are slow and right mouse button is not responding (it reacts only sometimes):

    2.Windows 7 clients and older Windows 10 builds (1703, 1607) are working with RemoteApps normally;
    To work around this problem, you can try to change the value of thepolicy Use Advanced RemoteFX graphics for RemoteApp in the local GPO editor (gpedit.msc) to the Disabled state (GPO section: Computer Configuration -> Policies -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Remote Session Environment);
    To fix the problem radically, you can roll back the current Windows build to the previous version (Recovery Options -> Get Started -> Go back to the previous version of Windows 10); However, there is also a workaround, which is to replace the RDP client version with an older one.

    We have tried that setting for remoteFX and that made no difference for us.
