Hi @poldi1405,

Thanks for reporting this issue.

Could you confirm if the same issue occurs on the latest development build?

You can install it by following the instructions shown here: https://www.sublimemerge.com/docs/linux_repositories#pacman

Additionally, could you try the following:

1. Open a new tab in Sublime Merge
2. Close all the other tabs (except the new tab you created)
3. Close Sublime Merge
4. Start Sublime Merge

After these steps have been performed, do you still see the slow start-up speed?

Thanks, - Dylan

Still happens in 2053

No noticeable difference.

Is there maybe some kind of hidden switch to disable the fork to background so I can easily export a strace?

Hi @poldi1405,

Thanks for the additional information! A trace would be much appreciated.

In order to use strace with smerge, you can pass the --multiinstance flag to smerge e.g. strace -r smerge --multiinstance

Thanks, - Dylan

It seems to hang polling a pipe…

The blocking call is at line 4475 trace.zip

Just checked. The same polling happens in Sublime Text 4 (dev) Build 4012, also Filehandle 13. Maybe something to do with the GUI library?

[mpldr]

I just started it on Cinnamon (X11) instead of sway (wayland) and it started near instantly, so this might be the reason.

[mpldr]

Update: it does not start at all anymore… it just seems to freeze at some point while starting up strace.zip

I've let it "run" for quite a while but this hangup is all I get out of it.

Seems this issue resolved itself by restarting the computer.
