How to get rid of annoying line when scrolling in web browser

I'm now using the KDE 3.11, as when I tried the TDE it was always a line of distortion across the screen when scrolling with the web browser (tried several).

My PC is an ASUS VivoBook Model L203MA - 2 x Intel Celeron Prosessors N4000 CPU @ 1.10 GHz - 4 GiB Ram - 1366x768 Mesa Intel UHD Graphics 600 (GLK 2) The X.Org Foundation.

Can someone help with this issue as I would like to try the TDE again?

Kind regards John

Re: How to get rid of annoying line when scrolling in web browser

You should be able to resolve this by pasting the code below into a text file. save it as xorg.conf and then as root copy it to /etc/X11/

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
## Option      "AccelMethod"  "sna"
   Option      "TearFree"    "true"
##  Option  "TripleBuffer" "true"
##  Option      "DRI2"    "true"
EndSection

If all goes well and the line vanishes you can then try removing the ## at the beginning of the lines starting with the top one and then testing after each change.

You will need to be editing the file as root as it is in the system area. After each change log out and on the Session button click down to Restart X - or just reboot whichever you prefer.

I always install a bit of software called Midnight Commander ( in the repos as mc ) It's an old school 2 pane file manager/editor that does not need X to run. So, on those days when you start up and all you get is a command line login screen you can still log in and use sudo mc to go and edit whatever file you just changed - uses the f4 (choose mcedit) to edit and f2 to save - you'll see the info at the bottom of the screen. I suggest you use it a bit first to get the hang

Good - the other thing I remembered is that in Control Centre>Desktop>Window Behaviour>Translucency I enable Translucency, but uncheck all boxes on all 3 tabs except for the Use OpenGL Compositor option. That may or may not be available on your machine, I have an old Intel 2500 chip.

To see all the options in Control Centre you first need to run

sudo kcmodules --unlock
