Yesterday I posted an issue, but it turns out this is not exclusive to looking glass. While in X11 session, I experience diagonal tearing. This can be noticed while using an AUR version of Google Chrome, for instance. Switching to Wayland solves the issue. This started after update 2022-11-02.

By the way, I also use the Sweet KDE theme and blurred background in the Konsole. The blur effect too doesnāt work after this update.
For this you can do two things:
- uninstall
xf86-video-inteland just delete/etc/X11/xorg.conf.d/20-intel.conf - or edit the
/etc/X11/xorg.conf.d/20-intel.confand make it like this:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
Option "TearFree" "true"
EndSection
and you can use also Option "TripleBuffer" "true" if you want ā¦
Since you seem to use video passthrough for the Nvidia GPU
the use of prime-run <application> is out of question to see if tearing persists ā¦
Was updated 5 days ago, so you might want to check if you also have the update. https://store.kde.org/p/1294174
If not, try to see how it goes with the default theme.
I tried this option. It causes my system to halt at systemd startup log screen.
What is the command to do this? This doesnāt even seem to be installed.
If you did not had it installed, then by adding the file /etc/X11/xorg.conf.d/20-intel.conf would create an issue, because the i915 driver is not quite the same as the intel driver that in that config is set to use.
pamac install package - is to install a package
pamac remove package - is to remove a package
But all this can be done from Pamac UI aka Add/Remove Software.
This solves the issue of diagonal tearing, but it does not solve the issue of blur. And looking glass still has diagonal tearing and reduced framerates. This issue does not exist on Wayland.
And I checked - I have the latest version of Sweet KDE.
Is blur effect activated? How is it set?
Is the Compositor enabled in Display Settings?
I enabled those, but after the installation of the driver and those options enabled, there is a stuttering effect when I drag my windows.
(Edit) P.S. The problem with blur is not my primary concern - the framerate drop and diagonal tearing in my looking-glass output is.
Right, so did you try to check with the 5.15 kernel that is LTS ?
LTS version of kernel forces my monitor to not exceed 60 fps. This is a common bug for my machine that was fixed only in Kernel 5.19 at that time.
Do you really believe your eyesight can go above that?
Anyway ā¦
But in the end, did you or not rebuild the AUR package as i hinted on your other topic?
From the LookingGlass documentation, it seems it passes trough whatever GPU there is, without the need of a separated dedicated GPU, so, why are you keeping the RTX 3060 via vfio-pci ?
Yes, absolutley and wholeheartedly. I see a very clear difference between 60-70 and 120-160. Itās quite obvious from the cursor movement.
I donāt know whether it can work without a dGPU (it probably can), but pretty much everyone using it relies on dGPU passthrough since the primary mission of it is low latency lossless quality video output. Which is a good thing for for gaming.
I donāt need my RTX3060 since all the use I have for it is almost exclusively on my vm. I could potentially set it up another way - try and pass it over to vm upon the start and return it to the host later, but this is a bit more technical than I can currently manage.
Btw. After I installed the driver xf86-video-intel and enabled TearFree, it behaves a bit strange when it goes to sleep and then wakes up. I see a black screen upon a wakeup and a mouse cursor. Any action I take does not give me the splash screen, it stays black. Only after I force-shutdown my machine and restart, the thing disappears.
Also, Itās not my eyesight that let me notice that the problem truly existed - I went into the settings ā desktop effects ā show FPS. It was consistently showing 60 fps at the kernel versions below 5.19. Also, looking glass itself wasnāt exceeding that (there is a debug option that lets you view your output FPS, it was showing 60 too).
Cool, you have time to watch the cursorā¦ Definitely we are talking about different things and probably there is a monitorās refresh rate to the mouse poll rate āconnectionā ā¦
What do you mean?
So you are using it for vfio-pci passthrough for a VM, is it for LookingGlass and that one flickers, then why we talk about your intel GPU?
Ah, ok ā¦ the common XY problem with an addition of ZQ too ā¦ Well, i hope someone will help you out.
Hell yeah, thatās helpful.
I came here with problem X, which didnāt exist before the most recent update. I came here because the creator of the software I was having problems with pointed me in your direction. Then this problem got worse and I came here again. You told me a solution to this problem - this solved X partially and created the problem Y, which I reported, providing further details of what happens to me if I do what you ask - thatās what people do when they want to help other competent people solve the problem, right? You start asking me questions about my time, my sight, and why I need vfio-pci. Yeah, tell me Iām the one creating the XY problem. You know, just a friendly suggestion - maybe you should research just a tad bit about why monitors with 300Hz even exist and why people even do vfio-pci, and how exactly they do that, before giving me advice about these.
Let it be your XY problem now - I put an X over this distro, because Y I even bother if the first advice people at VFIO give when you tell them that you use Manjaro is to switch to Arch/EndeavourOSā¦
Ban me now. That would be an ultimate help - this is what this forum is about after all, right? Changes nothingā¦
You mark the solution X and open a topic for problem Y then, and try to solve that. Thatās how this forum works.
Is not like on any Arch based distribution you will not have issue with AUR packages, and you didnāt even bother to answer if you indeed rebuild those related packages.
You should get informed, so you donāt have to ask for help, then complain about it.
For marketing purposes mostly. Because some people actually believe that human sight is limited only by our available technology. Is not so. Most of us are not even capable to perceive 60 cicles of flashing light, because most of that information is lost between the retine and our brain = Critical Flicker Fusion, and because
There is no disclaimer that states that a solution would be provided no matter what. Nobody is even tied to provide any sort of assistance if they donāt want. You should read the Forum Rules - Manjaro
There is no such thing as ultimate help, except your strawman.
Then, because i didnāt say it, but somebody else did - Be the change you want to see in the world!
