I'm still aware of a few issues that may cause freezes, but haven't seen anything causing a CPU spike.

Can you try the latest version setting WAYLAND_DEBUG=1 (e.g.: WAYLAND_DEBUG=1 clipmon).

Do you see an endless loop of logs when the freeze happens?

unfortunately no.. here is the output:

then localc freezes.

I played a bit around with the code and the situation improved when blacklisting the internal offer "application/x-libreoffice-internal-id-58731" (the id changes!) for selection. On copy, it still freezes. This second freeze I could reduce by further blacklisting "text/richtext" but sometimes is still freezes! its all very strange.

Just to be clear: the CPU spike happens in LibreOffice, not clipmon. It does not always happen though, sometimes it just idles around...

~whynothugo 4 months ago

Can you try with the latest HEAD? It has a small change to avoid operating on invalid mime-types (which Firefox also exposes), which may be the issue.

~gabm 4 months ago

that looks good! I couldn't produce any lock-up, great!

I will continue to use clipmon and we'll see. Thank you!
