Nvidia driver causes Xorg to use 100% CPU and huge lag when dragging OpenGL app windows

[Daniel van Vugt]

Nvidia driver causes Xorg to use 100% CPU and shows high lag and stutter... but only when dragging glxgears/glxheads, or any window over them. Other apps do not exhibit the problem.

Bug confirmed in two separate window managers so far:

  * Mutter / Gnome Shell

  * Metacity

[Daniel van Vugt (vanvugt)]

Xorg profile of when I was just moving the glxgears window.

[Daniel van Vugt (vanvugt)]

Workaround:

  env __GL_SYNC_TO_VBLANK=0 glxgears

This seems to be why unsynchronized apps like glmark2 are unaffected by the bug.

A video showing the lag.

[Daniel van Vugt (vanvugt)]

The bug is also in nvidia-410.93 and nvidia-418.30 :(

[Alexandr Oleynikov (devilspepper)]

I don't think it affects just glxgears, I experience it with pretty much any app that utilizes opengl, like Chromium or any Electron-based app like Slack or Discord.

[Daniel van Vugt (vanvugt)]

Yeah, it seems to be a general type of OpenGL application.

[Daniel van Vugt (vanvugt)]

Possibly related: "OpenGL yield behavior" in http://us.download.nvidia.com/XFree86/Linux-x86_64/455.38/README/openglenvvariables.html

[Daniel van Vugt (vanvugt)]

This is still affecting focal in driver version 390 but 410 and 418 don't seem to exist anymore(?). It would be interesting to see if later versions still have this bug...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

On second thoughts this might not be the only "lag" type problem affecting Nvidia in jammy. I can't actually reproduce it with GTK4 apps myself, but can with more traditional OpenGL apps.

Can anyone affected please try:

  * Disabling the 'Desktop Icons NG' extension in the Extensions app; or

  * Logging into 'Ubuntu on Wayland' instead?

[Kes (mr-kyem)]

Updated today to 22.04 and started noticing this issue as well.

easy to reproduce when chrome have video or any kind of animation happening.
If there are only static pages (like text). There are no lag. This affects all window dragging.

* terminal
* files
* other apps
* also chrome itself

Once chrome tab with animation/video/charts is closed or no longer active, everything start working fast again.

Only interesting err from journal:
```
google-chrome-beta.desktop[5530]: [5695:5695:0507/003622.561907:ERROR:shared_image_manager.cc(228)] SharedImageManager::ProduceSkia: Trying to Produce a Skia representation from a non-existent mailbox.
```

[Mikael Bendiksen (unk1nd)]

Having this issue as same as Kes describes.
Can be reproduced under Xorg environment running Nvidia 510 drivers and Ubuntu 22.04.
Did not have this issue under 20.04.

If I have a youtube video running the chrome window lags and the terminal window lags while moving them. If I have this page open it moves without lag.

I tried to disable Desktop Icons NG, it helped the issue a bit, but there is still extreme lag.
Using Wayland seems to solve the issue, but there are still programs like OBS that I need to use that can't capture the desktop ( not related to this ).

Running glxgears also give me lag while moving the window.

Let me know if you need me to try something specific that might help you get more data out.

That was meant to be fixed in OBS Studio 27 (bug 1838967). If it's not working in Ubuntu 22.04 then please open a new bug.

There is already a separate report, but it is marked as a duplicate of this issue. Is it supposed to be circular like that?

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-510/+bug/1970413

[Daniel van Vugt (vanvugt)]

It's not circular. Bug 1970413 is closed because it's a duplicate of this bug 1799679.

[Daniel van Vugt (vanvugt)]

Nvidia's latest assessment is that this is indeed a driver bug so we don't need to keep the mutter and metacity tasks open here...

https://gitlab.gnome.org/GNOME/mutter/-/issues/2233#note_1538392

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Rodrigo (ro-goab)]

Happy 4 years for this bug!

I have a 3070ti, the desktop is empty with nautilus, and moving the window is frustrating, too laggy.
However I can play steam games without problems or train ia models.

[Dimitris Moraitidis (dimisjim)]

also affects new 520 driver

[Daniel van Vugt (vanvugt)]

NVIDIA says the fix is coming in driver 525:

https://gitlab.gnome.org/GNOME/mutter/-/issues/2233#note_1575235

[Daniel van Vugt (vanvugt)]

Workaround coming in mutter 43.1?

https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2652

[Daniel van Vugt (vanvugt)]

A proper fix has now been released in NVIDIA driver 525. Confirmed by multiple users.

[Daniel van Vugt (vanvugt)]

Also verified fixed myself, using:

[Rodrigo (ro-goab)]

I am using 545.23.08 and this problem is still affecting me. It's surreal to buy a graphics card for over a thousand dollars and have the drivers be unable to move a window without lag

[Daniel van Vugt (vanvugt)]

Please open a new bug about that because this one is closed.
