--- Comment #2 from Ovear <ove...@gmail.com> --- Yeah, i do notice that too, but it's seems the result that compositor lagged[1]. And it may noe caused this problem i think, since there are actually a number of ubuntu and debian users reported it to upstream[2][3][4]. I also found multiple bugs in bugs.kde.org which mentioned this[5], but seems none of it is related to "compositor lagged continuous". Since there are no more detail logs in Xorg and kde, we think we may try to find a way to figured the root case which caused it. May be more verbose log or flame graph through efbp(with SystemTap or perf)? I am not familiar with kde an Xorg, so i have no idea how to apporach it. I am still trying to isolate this case, and see if I can find out more detail about this.
