Stuttering, then unresponsive screen #6089

Open cnt0 opened 3 years ago

cnt0 commented 3 years ago

config and log: here (essentially just a default config; I also filtered ipc-server.c and config.c events out of this log) sway version: 1.5.1 mesa version: 20.3.4-3 (from archlinux repos) video driver: i915

what happened: I started wf-recorder and launched a task which outputs some text to my terminal (alacritty). As you can see from the screencast there's stuttering (or how to call it), which persists even after I close alacritty and any other program. At some point sway stops updating the screen at all, so the only option is to switch session and kill it.

I've had this exact same problem for the past few weeks, but I didn't find anything useful in my logs so I thought my hardware was just failing.

I tried Sway master branch from Feb 22 1.5-aac1582e to Mar 4 1.5-d358aab8, and then switched to sway version 1.5.1 from the arch packages. The stuttering has continued with all versions.

Using applications like Discord sometimes causes the stuttering to start, and video calls using Google Duo in Firefox caused Firefox to lockup. In sway master branch if I killed Firefox, sway itself would also crash, but in 1.5.1 it does not.

Since I thought it was hardware failure I didn't save any logs, but if it's not then I'll consider trying again.

it's definitely not a hardware failure because I see no such problems in, for example, KDE plasma

I've also been experiencing this issue for a few weeks, and had just assumed that my 11 year old laptop was finally giving out, so I didn't bother the maintianers about it. Props to you for opening this!

If the problem appeared a few weeks ago, then it could be linked to an update around that time, e.g. mesa or kernel. When sway stops updating the screen, is sway using any resources? CPU, memory? Is there anything in dmesg?

Since you're using the i915 driver, I'm guessing it's related to the intel-driver bug. Here's my now closed report on the intel-driver: https://gitlab.freedesktop.org/drm/intel/-/issues/3099 There are heaps more of the same sort in the same issue-tracker.

@jonaslu thanks for link, I'll try it. I see no system-wide stuttering anymore, presumably after one of recent archlinux updates, but firefox still shows this behavior.

I'm not closing this issue because there were other people affected. @proudmuslim-dev ?
