Hi windows engineers:

i am using remote desktop in seamless mode to access a remote windows virtual machine application in my local PC. then i found most of the time the rdp session does not work when the remote application is browser(chrome or edge).

it is strange that occasionally, when the remote windows virtual machine bootup at the first, the seamless mode chrome can work, but most of the time the chrome rdp session connects successfully but there is no response for keyboard and mouse. also all of the time, the rdp session of edge can not display at all, but it seems the rdp session is connected.

the windows version is 22H2 of windows professional. and update at the point of KB5044285 installed at 2025/3/13. My windows OS is for ARM version.

i create seamless mode rdp session as the guidance of remote app tool with the link :
https://github.com/kimmknight/remoteapptool?tab=readme-ov-file and it seems works well for other application. so i guess it may be an issue of compatibility of browser and rdp.

what is your suggestion for this issue, is it a known issue?

    Hi Baowen,

    Thank you for letting me know about the issue with Chrome and Microsoft Edge freezing in seamless RemoteApp sessions. My investigation suggests that the behavior is linked to how Chromium-based browsers manage GPU-accelerated rendering and sandboxing in a RemoteApp environment. To help you restore normal functionality as quickly as possible, I have prepared the step-by-step troubleshooting guide below. After completing each step, please relaunch the browser in seamless mode and check whether the keyboard and mouse respond correctly..

    I) Disable GPU acceleration:

    Chrome / Edge (manual method)

    1. Open the browser.
    2. Go to Settings › System.
    3. Turn off “Use hardware acceleration when available”.
    4. Close all browser windows and relaunch.

    RemoteApp command-line method: If you publish the browser with RemoteAppTool, edit the “Program path” to add these flags:

    chrome.exe --disable-gpu --allow-no-sandbox-job
    (or msedge.exe --disable-gpu --allow-no-sandbox-job)

    II) Update the Remote Desktop client on the local PC:

    Minimum version: 1.2.6227 or newer. Download the latest installer via this link.

    After updating, restart the PC.

    IV) Install the latest cumulative update on the Windows 22H2 VM

    Please make sure the guest OS is at KB5053657 (March 2025) or later:

    1. Sign in to the VM.
    2. Settings › Windows Update › Check for updates.
    3. Install all pending updates, then reboot the VM.

    Let me know how far you get with these steps or if you need further support.

    Finn Dang.
