最新换的机器用的intel的核显,设置为4K, 60hz刷新率,但是页面经常掉帧,是不是卡一下,不知道有没有大侠遇到过。

掉幀是在什麼情況下發生的呢?可以參考一下 ArchWiki 的文章

Try other non-end-of-life kernels, currently they are: 5.14, 5.10, (5.15-rcX (it is beta version)).

When it starts to occur, after what actions - what you did or changed?
How did you recognize that the problem is in software and not in hardware?

If it is hardware-related, may be other cable could fix the issue?

@alven thanks!!! after update 5.14 kernel, everything is ok !!!
