Screen tearing.

[agoodfellow123]

Hello I'm having a screen tearing issue, I'm assuming nscde doesn't come with a compositor. So I installed picom however it completely bugged out the background (tiles doesn't repeat) so I decided to ask here, is there anything we can do about screen tearing?

Hi @agoodfellow123,

Which version of fvwm? Which OS/Distro? I have seen this non-repeating tiles on Fedora 37 already, but have attributed this to virtualisation driver.
Is this what you are describing on the host machine, or some virtual guest? If guest, which virtualisation (KVM, Vmware, VirtualBox ...).

Hello sorry for the late response, my setup got broken unfortunately so I had to reinstall. I was using Manjaro at the time. I was using AUR version. I actually build some of the packages myself but I don't remember which ones. After I failed to build one of the packages I gave up and installed it from AUR.

So if this is not repeatable and doesn't exist, can we close this issue?

i have the exactly the same issues on both of my Debian 11 tablets with NsCDE. I have to use NsCDE without compositors. I launch xcompmgr / picom only when I want to use OnBoard's draw-on-desktop function.

Every device I have has NsCDE installed and all of them has screen-tearing issue but I don't mind...

Hi @normandy8757675

I don't have any Linux tablet available near me for now, and I didn't noticed screen tearing issue anywhere except on new VirtualBox 6.0.X where things are still buggy.

What are your other devices? I'm testing/using NsCDE on 3 different notebooks, bunch of KVM VM's, couple of VirtualBox and on RPI4.

Hi @NsCDE ,

I am experiencing this same screen tearing issue. I installed NsCDE on SparkyLinux. I originally had the MATE desktop environment for what it's worth. On an 8 year old PC: GTX 970, i7-4790k, some old Radeon SSD for the OS drive.

I really like this DE but the screen tearing can be annoying sometimes. Please, can someone tell me how to use NsCDE without compositors? I don't know my way around NsCDE and don't know where the relevant settings would be.

BTW--I am not sure if this information is useful--SparkyLinux allows users to install lots of different DEs through its APTUs App Center. It's how I installed NsCDE. Just one click in the software center, and then pressing enter in the terminal. Then of course I restarted and selected NsCDE in the login screen.
I think a similar thing can be done with GhostBSD, which uses MATE.

Hello.

Are you using a closed source video driver or an open source one?

If you are using a closed-source driver, install the package named picom and, using the .xinitrc file, add the following lines:

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

nvidia-settings -a 'AllowFlipping=0'

picom --backend glx --xrender-sync-fence &

Make .xsessionrc file executable with command chmod +x .xsessionrc

Logout and login again.

Isn't screen-taring just a biproduct of X11?
