There seems to be cases where Windows does not activate the newly launched Linux GUI app and set it to the foreground. You might need to click another window or desktop before you can set the keyboard input focus back to your Linux GUI app in such cases. The new version 3.8.2 addresses this problem, and you should now always be able to set the input focus simply by directly clicking on your Linux GUI app.
The new version 3.8.2 improves ensuring the initial visibility of your Linux GUI apps. For example, JetBrains Toolbox that places itself to the top right corner of the desktop screen should now properly show its window title bar as well as its full content even on HiDPI monitors.
