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)
- Open the browser.
- Go to Settings › System.
- Turn off “Use hardware acceleration when available”.
- 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:
- Sign in to the VM.
- Settings › Windows Update › Check for updates.
- 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.
