espanso periodically stops triggering

[twoprops]

Description

I seem to be having the same issue as #880, which was closed without ever apparently being resolved. Espanso 2.2.1 installs and works normally on my Fedora 40 (same problem with Fedora 39) running KDE/Plasma 6/Wayland. After a variable amount of time (seconds to maybe a day, hard to say for sure) espanso will stop triggering on typing. It's still running: espanso status reports espanso is running. Hot keys still seem to work. If I have the trigger toggle enabled (I usually don't) I can toggle espanso and get the enabled/disabled messages, but it still doesn't trigger on text. Executing espanso restart will get it working again, but it pops up a little "Espanso is running!" window which causes loss of focus at which point it would have been much easier to type the full text instead of trying to use an expansion.

Steps to reproduce

1. start espanso (from locally compiled binary)
2. happily use espanso's awesome text expansion capabilities
3. a variable amount of time later, espanso stops expanding text, though still responds to hotkeys
4. only a restart of espanso will restore function (toggling, for example, does not)
5. continue at step 2

Expected behavior

espanso would continue to trigger and expand text

Self-service

• I'd be willing to fix this bug myself.

It seems that this is a known issue with Wayland that is being attended to but delayed due to limited resources. If anyone else encounters this, I implemented a mostly-effective workaround using cron: use crontab -e to edit your local crontab, and add:

*/15 *  *  *  * /usr/local/bin/espanso restart >>/dev/null

This will restart espanso every 15 minutes. I have noticed that on Fedora 40, the little window that pops up saying "Espanso is running!" no longer steals focus as it seemed to in Fedora 39 (or there was a change in Espanso) -- such a change in focus would be really annoying occurring asynchronously so the workaround might not be viable with Fedora 39 or other distros that behave similarly. Also, even with restarting every 15 minutes there are still times that Espanso is unresponsive when I try to use it, and I suspect that, should a restart occur in the midst of typing a trigger, it will prevent Espanso from triggering. Overall, though, this seems to be a good mitigation strategy while the new Espanso team gets up to speed.
