Windows 10 1903 へリモートデスクトップ接続すると数分で画面描画が固まる（操作はできてる）
理由はわからないけど。
とりあえずワークアラウンドがあるようなので適用して様子見してる。
Based on my research, it's an issue with Win 10 1809 to Win 10 1809.Now please have a try with the method below:
You can work around this by disabling UDP session used by MSTSC on your affected computer (the one where they're running the Remote Desktop client).
Run gpedit.msc.
Navigate to Computer Configuration > Administration Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client.
Set the "Turn Off UDP On Client" setting to Enabled.
