XPS 13 7390 Screen tearing

I just got the new XPS 13 7390 (without touchscreen, 1920x1080 res, i7-10510U) and I'm suffering from the classic screen tearing. I decided to buy a laptop without a discrete GPU because I thought the general consensus said, that integrated graphics are more solid than discrete. I know that this is bleeding edge hardware and I took the risk.

I have a clean install with LXQT and bspwm as WM.

The tearing happens whenever I have a full screen video on Chrome/FF OR whenever I DON'T have a fullscreen video on mpv. Strange huh?

I've read top to bottom the wiki for Intel Graphics/Hardware acceleration and tried almost all the combinations. By using the xf86-video-intel along with their X11 configs (TearFree etc), chrome gave me extreme glitches and was unresponsive, kitty (gpu terminal) too. Thus currently, I'm using the modeset driver. Moreover, I've installed intel-media-driver, libvdpau-va-gl and I've set the following envs

LIBVA_DRIVER_NAME=iHD
MESA_LOADER_DRIVER_OVERRIDE=iris
VDPAU_DRIVER=va_gl

Also I tried compton and I tweaked GPU related browser flags, without any luck.

A few outputs

➜ glxgears
    324 frames in 5.0 seconds = 64.609 FPS
    301 frames in 5.0 seconds = 60.031 FPS

Re: XPS 13 7390 Screen tearing

Why are you using libvdpau-va-gl? Where did you set your environment overrides? Also, (and just for my own personal edification) have you tried with xf86-intel-video and also enabling both GuC and HuC loading (i.e passing enable_guc=-1)? If so what's the behavior? Is the behavior different with a full DE (i.e Gnome or Plasma)?

 $ dmesg | grep uC
[    4.539235] [drm] HuC: Loaded firmware i915/skl_huc_ver01_07_1398.bin (version 1.7)
[    4.549819] [drm] GuC: Loaded firmware i915/skl_guc_32.0.3.bin (version 32.0)
[    4.560061] i915 0000:00:02.0: GuC firmware version 32.0
[    4.560065] i915 0000:00:02.0: GuC submission disabled
[    4.560067] i915 0000:00:02.0: HuC enabled

Have you looked at Phoronix's latest write-up for same family hardware?

Re: XPS 13 7390 Screen tearing

Excuse my ignorance on that topic, its out of my area of expertise. I was following the wiki, which states, to configure VDPAU with intel GPU, we need to set VDPAU_DRIVER to va_gl. Before installing libvdpau-va-gl, vainfo threw errors. I set the envs once in .profile and once in LXQT session manager. Also I used https://github.com/intel/media-driver because of Ice Lake support.

I tried multiple combinations of enable_guc in conjunction with the old driver but with no luck. I've followed both the wiki and this guide along with the recommendations in comments. To clarify something, I prefer not to use that option, because the wiki states that GVT-g doesn't work with this option and I'm very interested in deploying a VM on that machine, my work depends on a few osx/ms products and I would like a decent performance.

Thanks for the link, I've missed it somehow. I believe the Intel "Iris" Gallium3D driver is the env MESA_LOADER_DRIVER_OVERRIDE=iris which I have? May I test mesa 19.3 instead?

In another story, if on wayland then the tearing is gone. I tried sway, to avoid the whole DE bloat, and the performance was top notch. But I'm trying to avoid wayland for now, a lot of my workflow stands in X tools. In the case of a no solution, I'll migrate there

Re: XPS 13 7390 Screen tearing

All of the situations you describe are where I'd expect tearing to kick in because the software in question might disable the compositor, e.g. specifically for MPV see: https://wiki.archlinux.org/index.php/Mp … compositor

Fullscreen will probably trigger similar functionality in compton: https://wiki.archlinux.org/index.php/Compton#Flicker

Re: XPS 13 7390 Screen tearing

In addition to V1del's notes re: fullscreen - I would double-check that you actually need to use the VDPAU try removing that from the equation and testing (what were the errors that vainfo was throwing without libvdpau-va-gl?).

Intel media driver makes sense, you should only have to set the following variables (maybe trying setting these in /etc/profile.d/):

export LIBVA_DRIVERS_PATH=<path-contains-iHD_drv_video.so>
export LIBVA_DRIVER_NAME=iHD

Others with more knowledge will chime in I'm sure.

Re: XPS 13 7390 Screen tearing

Hmm by adding in compton.conf

unredir-if-possible = false;

tearing gone! Should I let it in this state, swallow it and wait for similar issues to come up, or should I trace the root problem?

About the VDPAU, it threw a kind of "no such file or directory" error. It looked the drivers dir and there I had only 3 files (those wrapped in asterisks). After the installation of the lib it populated the rest

➜ ls /usr/lib/vdpau                           
*libvdpau_trace.so*  *libvdpau_trace.so.1*  *libvdpau_trace.so.1.0.0*  libvdpau_va_gl.so  libvdpau_va_gl.so.1
[/b]

As I said, I did many incremental experiments and I had out of the equation te vdpau at least 2-3 times.

In any case, thank you both!

[UPDATE]
Just to be sure and for the records, I disabled again vdpau & compton along with your above recommendations and the tearing reappeared

Re: XPS 13 7390 Screen tearing

To be certain to prevent tearing you have to keep the compositor enabled as far as I know. (FWIW on wayland nothing else happens, you simply cannot disable the compositor there with any method, but the protocol should be more efficient to alleviate any drawbacks)

The drawback of this is that this might give you some FPS loss if you are a heavy gamer or so. If this doesn't negatively affect your  perceived experience this pretty much is "the fix".

FWIW regarding the VDPAU discussion, I don't think this factors in here, your vainfo output showed that for VAAPI the correct driver would be used regardless, so you should generally configure all applications that have good VAAPI implementations to use VAAPI directly.
