Screen tearing in Chrome

[Antifreeze]

I'm not sure where to post this problem. But a little background will help. Everytime I use Google Chrome, it starts out working, after a while the top of the window starts to tear and disappear.
I'm using the open source nouvea driver in kubuntu 18.04

Has anyone had this issue or know of a fix?

thanks for reading

Have you ensured that hardware acceleration is enabled in chrome's advanced settings?

[Antifreeze]

It is enabled. This is a hard bug to reproduce. It seems to happen more than not when multiple tabs are open. The other weird thing is the fact that it only happens in Google Chrome, no other apps or browsers.

I also forgot to mention that this problem would happen in Linux Mint also. So after getting frustrated, I decided to change distros 2 months ago to kubuntu. I'm glad I did anyway it's a far better distro than Mint.

try this , first go to system settings>Display and Monitor>Compositor> and under "vsync" set to "Full Screen Repaints" click apply .

use that for a wile and see if it helps .
if not then try

sudo touch /etc/profile.d/Tearing.sh && sudo echo  export KWIN_TRIPLE_BUFFER=1 > /etc/profile.d/Tearing.sh

reboot and try for a wile , if of no help the you can remove the script with

sudo rm -rf /etc/profile.d/Tearing.sh

Thank You Vinny!
I made the setting in vsync. Also made 2 scripts and saved them in my scripts folder just in case.
Very much appreciated!

Just typed a whole replay and it disapeared. Anyway it started again in Chrome, so moved to Firefox. Also made a shell script in /etc/profile.d and put in
KWIN_TRIPLE_BUFFER=1 the script.
