我在 Blender 中的 GPU 上渲染时遇到奇怪的性能问题。例如，我的光标（以及整个 UI）偶尔会滞后，当尝试使用 ksnip 进行屏幕截图时，光标非常难以移动，因为它滞后很多。这似乎只在渲染时发生。
我已经成为 Debian（也使用 Plasma）用户几年了，最近决定尝试 Manjaro（通过 Architect 安装，因为我还没有找到在图形安装程序中按照我想要的方式对磁盘进行分区的方法）。我在 460.56 驱动程序版本的 Debian 10 上没有遇到类似的问题。
我正在谈论的内容的一个小演示：https://i.stack.imgur.com/q9iya.jpg
upd：我注意到，当这种卡顿发生时，Xorg CPU 使用率会增加到约 10%。
