BlenderのGPUでレンダリングすると、奇妙なパフォーマンスの問題が発生します。たとえば、カーソル（およびUI全体）が頻繁にレックを生成し、ksnipを使用してスクリーンショットを撮ろうとすると、カーソルがレックが大きすぎて移動するのが非常に困難です。これはレンダリング時にのみ発生するようです。
私は何年もDebian（Plasmaを使用）しており、最近Manjaro（グラフィックインストーラで目的の方法でディスクを分割する方法が見つからなかったため、Architect経由でインストール）を試してみました。 460.56ドライババージョンのDebian 10でも同様の問題は発生しませんでした。
私が言う内容の簡単なデモ：https://i.stack.imgur.com/q9iya.jpg
upd：この途切れが発生すると、Xorg CPUの使用量が約10％まで増加することを確認しました。
