修正する：Intel i5 10世代CPUという点は注目に値します。
私は最近、新しいLenovo ThinkPad Carbon x1（第8世代）を購入し、ここにDebian Busterをインストールしました。すべての最新パッケージをインストールし、ファームウェアのアップグレード（非無料バージョンでもアップグレード）を実行した後、Firefoxおよびurxvtで0.5秒から10秒間続く一時的な停止が発生したことに気づきました。これは、ディスプレイの更新が中断されたことを意味します（マウス入力は、キーボードが一時停止した後に表示されます。
TTYはすぐに変更され、画面の固定が解除されることがあります。 dmesg、Xorg.0.log、またはジャーナルctlにも関連ログはありません。私の言うことは、このような中断が発生した特定の時間に我々はログをまったく書いていないということです。私のシステムには、多くの空きメモリ（16GB）と多くのスワップスペース（やはり16GB）があります。これは1分以内に何度も起こり、Firefoxを使用するときはもっとそうです（私の考えでは）。
どんなアイデアがありますか？よろしくお願いします！

答え1
私もこれがi7ランタイムブレーカーであることを見ました。 AFYIオーディオが動作している場合、音は途切れることはありません。 glxgearsを実行し続けると動作は停止しますが、コンソールログには同じ速度の3pfps（4Kモニタ）が表示されます。
長年バスターを運営してきました。この動作は比較的最近（おそらく数ヶ月）です。あなたのように私もXorg（waylandではない）を使用しますが、cinnamonとlightdmも使用します。
そのため、グラフの更新が停止し、操作が続くと思います（マウスを動かしたりウィンドウをドラッグしたりするなどの操作が発生しますが、数秒間画面に表示されません）。とても残念
