I have a weird problem I don't know how to solve or even to debug.
I copy (in general, no specific application) with CTRL + C and paste with CTRL + V.
I would say that 70% of the times I use CTRL + C the copy fails and, when I paste with CTRL + V, I'll paste the content that was already copied on the clipboard.
If I hit CTRL + C like three or four times, the content will be copied but, on the first time, it will almost certainly fail.
Can somebody, please, give me any ideas on how to solve this?
I found out this was related to the focus policy.
Since I had mouse focus policy configured, sometimes CTRL + C would not copy since the window I was trying to copy from did not have focus.
I changed the focus policy to follow click instead of mouse, and the problem seems to be solved.
