100% CPU from time to time

[Iey4iej3]

Mogan Version

1.2.5.5

Operating System Version and Architecture

Debian 12 under Sway WM (Wayland)

Describe Bug

It happens frequently that the CPU usage becomes 100% and the system gets stuck.

I do not remember the same thing in slightly earlier subversions of 1.2.5 LTS.

Expected Behavior

This should not happen.

We have not started the Wayland support, I suggest that you should you Xwayland.

I'm using Debian 12 KDE Xwayland for developing Mogan. Debian 12 is the recommended operating system, but Wayland is not recommended for now.

Thanks for reporting the bug.

XWayland is of poor quality under HiDPI. In any case, "Wayland" is only for information (it might not be necessarily relevant).

I need a reproducer like https://savannah.gnu.org/bugs/?62156

[Iey4iej3]

I know. I have not found a way to produce it stably, and it is very hard to debug. Do you have dbgsym package for Mogan?

@Iey4iej3 I suggest you to have a terminal by your side and perf record -p <pid> -g when you observe that behavior. That would be really great. After a while, you can also force a coredump of the process so we can get an idea of the process state.
