Can't explain it, but a CUDA update fixed the clipboard here. Could be the same thing?

Interesting. We'll take a look.

Strange. It works now with an unknown condition.
Need to identify what's happening.

It does not work in most times and works seldomly. Need to find the cause.

I'm adding this to the list of urgent issues. @danisla

I feel that the core issue of this problem is that the clipboard is set multiple times to the same value repeatedly when it should be only set one time, masking the new clipboard value that is supposed to be set, and there is nothing to prevent this phenomenon. It also seems to frequently prioritize the clipboard value of the client instead of bringing the host clipboard value to the client.

Some kind of control is required to not make xclip do that.

I think it's a bit better because of some unknown reason, but not too sure.
