For screen tearing with Nvidia, try to create a file in /etc/profile.d/ with following content:
Let the file name be for example kwin_triple_buffer.sh
When you restart, the KWin triple buffer should be turned on explicitly and screen tearing should disappear.
Also be sure to check System Settings->Workspace behavior->Compositor-> set Tearing prevention to Full screen repaints.
Code:
export KWIN_TRIPLE_BUFFER=1
Let the file name be for example kwin_triple_buffer.sh
When you restart, the KWin triple buffer should be turned on explicitly and screen tearing should disappear.
Also be sure to check System Settings->Workspace behavior->Compositor-> set Tearing prevention to Full screen repaints.
