Ripples While Scrolling/Streaming Video

doxa · 2018-06-24 15:28:53

After installing Helium, I'm getting these "ripples" across my browser and other programs when scrolling. Any idea how to fix this?

As always, many thanks!

It's caled 'tearing' or 'screen tearing', you may find many topics with some search of the forums/google (And it can be a nasty thing to fix).

Strange. Wasn't occurring with the previous version..

this is likely connected to your other issue that still needs solving.

It might simply be a need to tweak your composition settings in ~/.config/compton.conf or /etc/bunsen/compton-startup.
BL Hydrogen launched compton with the option '--vsync opengl' but that has been omitted from Helium, because it is not necessarily ideal for all users.

For a test, try uncommenting line 219 (probably) in ~/.config/compton.conf to enable:
vsync = "opengl";
If that works for you, you could make it system-wide in /etc/bunsen/compton-startup on line 61, but you might want to consider the other options in those two files - something different might be better for your hardware.

(I don't think it's related to display brightness, but don't quote me.)

OK, so line 219 in compton.conf already shows #vsync = "opengl". By "uncomment" do you mean deleting this line? Thanks.

uncomment means delete the # at the beginning.

And this is dependent on whatever video driver, video hardware, and programs (browser and players) you are using. I know that with my Intel Skylake and Coffeelake GPUs, Firefox always has video glitches when scrolling when they use the default "modesetting" driver, and the only way to get rid of them is to switch to the "intel" driver instead. I also set the TearFree option with the Intel driver.

So making sure that inxi is installed and running "inxi -G" will show your graphics hardware and driver situation. It your hardware is listed as just a bunch of numbers, you may get a better result if you update your PCI hardware database first as sysadmin:

update-pciids

Thanks.

Enabling vsync opengl seemed to help a little, but not entirely. Still getting tearing, especially when in fullscreen mode.

How does it look if you disable compositing entirely?

How would I go about doing that?

dolly · 2018-06-28 22:40:36

^You find it in the preferences section in the right click menu. Or you can uncomment it in the autostart file. I always uncomment it, first thing I do on a fresh install.

What is it good for really?

doxa · 2018-06-28 22:48:54

^ Thanks for the clarification.
I disabled the compositing and it actually got worse.

tknomanzr · 2018-06-29 01:24:51

This sounds like a driver issue then. Did you manage to get Bumblebee working?

I haven't gotten Bumblebee working. I installed it thru the terminal, but not sure how to get it to work. Following the instructions returns errors all along the way.

I tried following this tutorial to install Nvidia drivers: https://www.youtube.com/watch?v=KUsnygrNUMw

But it resulted in the screen going black and freezing when booting.

I am no expert on this but I would follow the Debian wiki.

What the heck would Bumblebee have to do with scrolling artifacts with the Intel kernel modesetting driver?

I also have to wonder why you've ignored my advice so far, when I've encountered and fixed the same sort of scrolling issue with my Skylake and Coffeelake Intel GPUs...and others on the MX forums have also had and fixed the same issues using the same procedure---so much that we've added the fix to MX Tweak to make it dead easy to apply. I don't know if it will apply to your somewhat older GPU, but it's at least worth a try!

It's not merely a scrolling issue, it's definitely video tearing. Also, not sure how to implement your procedure. How do I switch to the intel driver?

I'm going in circles following endless tutorials to try to install the nvidia drivers and bumblebee, but only encountering endless errors and no improvement.

Someone with your hardware will have to step-by-step it for you, I cannot.

With a normal Optimus system, the Intel GPU is always handling the 2D output, such as for browsers and video. Bumblebee just allows the system to hand off the 3D rendering work to the Nvidia card, but it still goes back to the integrated GPU for the display. The "inxi -G" command lets you see this...if you'd ever run it and post the results like I asked.

Anyway, to make sure you're running the "intel" instead of the kernel modesetting driver, make sure you have xserver-xorg-video-intel installed (I think it should be by default), and put a file named "20-intel.conf" in /etc/X11/xorg.conf.d with the contents:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
#  Option      "AccelMethod" "uxa"  #could also use the default "sna"
   Option      "TearFree"     "true"
EndSection

and reboot. Inxi should show that you are now using the intel driver.
