--- Comment #2 from Luca Mastromatteo <lukycroci...@gmail.com> --- Nothing interesting from the dmesg. And yes, it seems to be the blur effect, no artifacts after disabling it. I didn't know where to put this since I didn't had problems with this driver since I've encountered in this. Output of the command https://paste.kde.org/pg6yqrbf9 Running kwin from the terminal, with and without the option enabled in kwinrc didn't changed anything.
