kwin_wayland CPU 超高

最近更新版本之后,电脑巨卡无比,发现什么都没有开的情况下kwin_wayland这个进程占用cpu就非常高

Re: kwin_wayland CPU 超高

得装 -debug 包啦。不过这儿有个 JIT 字样,不知道能不能看到些啥。总之你先按回车看看是在哪个库文件里,然后装对应的 -debug 包。腾讯云有 -debug 包的镜像。

Re: kwin_wayland CPU 超高

不会debug,看不出要debug哪个包?我对比另外一台电脑更新内容,看里面有linux-firmware-20240703.e94a2a3b-1,  盲猜是驱动更新有问题了,downgrade linux-firmware执行到上一个版本20240610.9c10a208-1没有问题了。

Re: kwin_wayland CPU 超高

最近一段时间感觉笔记本比较烫,打开 Zotero 或 firefox 后,kwin_wayland 的 CPU 占用在 7%-16% 间跳动,并且 zotero-bin 或 firefox 进程也保持相似的 CPU 占用率。
将 linux-firmware 降级无法解决。

目前尚不清楚原因。你说有影响吧,电脑整天很烫。你说没有影响吧,它又占着 10% 左右的CPU。无奈。
