Steps of reproduction

  1. Be idle until the monitors blank
  2. Wake up the system (e.g. move the mouse)

Expected behavior

Compton should continue operation like before

Current Behavior

Compton crashes because of the 144Hz monitor

Console log:

ev_screen_change_notify(): Refresh rate detection failed, --sw-opti disabled.Floating point exception (core dumped)

Thanks for reporting. I guess right now you could avoid this problem by disabling sw-opti

Can you get a stack trace of compton when it crashes?

Tell me if you need more.
Btw, you can force the screen blanking with xset dpms force standby

@zischknall Sorry, I meant a stack trace. e.g. can you run compton under gdb, wait for it to crash, and run bt in gdb?

@yshui tried it. As soon as i move the mouse and the screen stops blanking my whole xserver has locked up already by then. And i can't get the backtrace.
Doesn't happen without gdb tho.

@zischknall That's fine, the screen will stop updating, but you can still type in stuff. So you need to keep your gdb window focused, and when xserver locks up, you can blindly type in bt, enter. Then type q, enter, y, enter to quit gdb.

@zischknall Sorry, but your compton is built without debug symbols, can you rebuild it with debug info?

You can do that by passing --buildtype=debug to meson

@yshui
strange behaviour it didn't crash 5/5 when run in gdb but it still crashed when i ran it alone.

What would be suitable to measure the performance of swopti?

Edit: Nevermind i was just to stupid to run the right version. It just throws this now without crashing:

ev_screen_change_notify(): Refresh rate detection failed.swopti will be temporarily disabled

@zischknall

CPU usage, maybe? What prompted you to enable swopti in the first place?

It just throws this now without crashing:

This means the fix is working.

@yshui must have been a default at some point on my distro.

@zischknall Hmm, it is not in the default config anymore: https://git.archlinux.org/svntogit/community.git/tree/trunk/compton.conf?h=packages/compton

Anyway, is there any noticeable difference with/without swopti?

@yshui after quick testing i can only conclude that without swopti compton is using less cpu

@zischknall Thanks for the information. I guess it is better to stop using it then.

I will close this issue since it's fixed.
