Same here. Both Brave and Slack flicker randomly after updating to 5.15. Reverting to 5.13 resolves it.

Is this issue occurring across other distros? What could be causing it? Is there any more info i should provide?

bradleeedmondson commented 2 years ago

I believe I am seeing this issue too, with a PowerColor 6800 XT running PopOS 21.04 in a custom rig.

I see random flickering on both monitors with kernel 5.15, while booting with backup kernel 5.13 has no issue. Flickering affects whole display (including desktop background), not just specific apps/windows, but seems like it happens more frequently when using Chrome (I have full Google Chrome 96.0.4664.93 -- don't judge). The GPU has worked flawlessly up until a few days ago when I first booted with 5.15.

Showing the flickering issue: 5.15.5-76051505-generic:

I hope someone has an explanation for why this is happening, it seems i'm not the only one who's affected, i wonder why Pop 20.04 LTS upgraded the kernel so soon, did Ubuntu upgrade the kernel too?

Attaching dmesg output from a 5.13 (no flickering) and a 5.15 (flickering) boot. dmesg_5_13.txt dmesg_5_15.txt

I have this issue on a fresh install lemp10 laptop.

Please run inxi -F in the terminal and post the output here, the developers need as much info as you can provide.

Open terminal --> type inxi -F then press Enter --> select the whole output then copy it with Ctrl Shift C --> start a new comment here, press Ctrl E to insert code then paste the terminal output.

leviport commented 2 years ago

@guyvdbroeck Please include the OS version you did a clean install with, as well as the packages you installed after installing the OS. If I can recreate this on my lemp10 it would be immensely helpful for troubleshooting.

I was able to stop the flickering by adding intel_iommu=igfx_off to my kernel parameters. This on an Intel only machine with an iGPU and has been effective for a week.

Could you write a step by step instruction on how to modify kernel parameters? It would make things much easier for less experienced users, i often find the Arch Wiki too complicated, it never tells me how to do things and which commands i need to use.

You can use kernelstub as follows:

sudo kernelstub -a intel_iommu=igfx_off

This will add that kernel parameter to /etc/kernelstub/configuration and to the systemd-boot entries in /boot/efi/loader/entries/. For instance, after running that command above, the /boot/efi/loader/entries/Pop_OS-current.conf contains the following:

title Pop!_OS
linux /EFI/Pop_OS-241af729-d87a-45d0-9c76-a6db1260573a/vmlinuz.efi
initrd /EFI/Pop_OS-241af729-d87a-45d0-9c76-a6db1260573a/initrd.img
options root=UUID=241af729-d87a-45d0-9c76-a6db1260573a ro quiet loglevel=0 systemd.show_status=false splash intel_iommu=igfx_off

As you can see the kernel parameter we wanted to add is now on the options line.

Once you have added this parameter, you will need to reboot your machine for it to take effect.

If for whatever reason you want remove it (e.g. this problem is fixed properly, or this doesn't fix your flickering issue), then you can do the following to remove the option:

sudo kernelstub -d intel_iommu=igfx_off

I hope that helps. Note, this is not a proper fix... it is more of a workaround that I discovered from the Intel-IOMMU kernel documentation:

If you encounter issues with graphics devices, you can try adding option intel_iommu=igfx_off to turn off the integrated graphics engine. If this fixes anything, please ensure you file a bug reporting the problem.

bradleeedmondson commented 2 years ago

Just to confirm, is anyone else seeing this on amdgpu? I've observed this with both Radeon 6800 XT and 6900 XT on a Ryzen 7 5800X box. Obviously any Intel driver-specific issues aren't applicable there (nor is the intel_iommu kernel setting), so I'm trying to figure out if I should post a separate issue.

JorisVanEijden commented 2 years ago

intel_iommu=igfx_off did not stop or reduce the issue for me.

Steve-Z commented 2 years ago

Same problem here, running Pop!_OS 20.04 on a Dell e7470. Seems to be a horizontal flickering of maximized windows. I have seen it on Firefox 95, Slack desktop client (4.22.0), and VS Code (1.63). It is perhaps triggered by scrolling vertically, but can persist for some seconds even when I stop scrolling.

Pop OS has just updated the kernel from 5.15.5 to 5.15.8, the flickering is still occurring but less often than before, i think it might be fixed soon.

szul commented 2 years ago

I have not had this issue recently either. :crossed_fingers:

JorisVanEijden commented 2 years ago

On 5.15.8 it is very much reduced but not completely gone here. From avg 5 times a minute to about once every 5 minutes.

I'm doing a little better than that. Only a couple of times since I updated to 5.15.8. But not completely gone.

hexpunk commented 2 years ago

I am using a Lemur Pro 9 with a fresh install of Pop OS 21.10. All updates have been applied. I'm also experiencing this issue. I don't think it's related to Chromium as I have Firefox installed. The issue happens infrequently, but it's still disconcerting. I think I've seen it happen while on a fullscreen terminal window.

Sorry for what mostly amounts to a "me, too" post. I'm mostly just happy this is a known software issue and there's not a problem with my hardware. 😌

I'm not sure if this ticket is even the right place for this issue. Is anyone here working on this? It seem the application (I've only noticed it in Brave and Slack so far, my JetBrains IDEs seem unaffected) skips a frame in rendering so whatever is behind it is visible for a split second. Since the update to 5.15.8 clobbered my 5.13 kernel I've resorted to making my desktop background a screenshot of my most frequently used windows. That way the effect is slightly less jarring :)

JorisVanEijden commented 2 years ago

Update: disabling hardware acceleration provides a workaround for me. In Brave: Settings->additional settings->System->Use hardware acceleration when available In Slack: File->Preferences->Advanced->other options->Disable hardware acceleration

hexpunk commented 2 years ago

I just experienced it again in VSCode (Chromium-based...) while scrolling in the built-in terminal really fast. First time I've experienced it in days.

Steve-Z commented 2 years ago

For me it was better, not gone but better, for a while, since the 5.15.8 update.

But in the past 1-2 days it has been bad, specifically Slack desktop client and VSCode. I have not rebooted since the update. Could that be having an effect.

mohnishkodnani commented 2 years ago

I experience it in the Brave Browser mostly, however, not limited to that alone.

Has this been fixed? the radio silence for the last two months makes me assume so, but in case it hasn't: had similar issues after running Ubuntu 20.04 with kernel 5.15.x. I could solve the problem by updating mesa to the latest 22.0 build (which is still in RC phase as of now), or more specifically, just updating libgl1-mesa-dri was enough. I fetched the prebuilt package from here, but not sure if this will install on Pop, dependency-wise. If you want to try installing this and apt tells you it needs to install and remove a dozen other packages, then don't do it.
