[BUG] sometimes delay and less responsive when using DRI3 GPU Acceleration

[hgw77]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I am using the latest Debian XFCE image (debian-xfce-3aab897f-ls136). When I start the container, the desktop is fast and responsive. I like it very much, it feels fast and looks nice with composite activated 👍

However, sometimes I experience a noticeable delay, about half a second or more, for input/output actions, such as mouse clicks and keyboard input. This makes the desktop difficult to use.

At first, I thought this was a network issue, but I have ruled that out. When I restart the Docker container and open the desktop again, everything is back to normal: fast and responsive. Also I have the same problem on localhost.

I believe I’ve identified what triggers the problem, but I don’t know why it happens. When I open the XFCE terminal and type, there is no delay. But if I open Xterm and start typing, the delay appears immediately. After that, the delay also affects the XFCE terminal and the rest of the Desktop. This is the only situation where I can reliably reproduce the issue, although I have seen it triggered in other ways as well.

Once the delay starts, it persists even if I reload the browser or switch to another browser. The only way to fix it is to restart the entire Docker container.

Expected Behavior

No response

Steps To Reproduce

1. run debian-xfce-3aab897f-ls136 with DRI3 GPU Acceleration
2. connect to the desktop on https://localhost:3001
3. open xfce-terminal, move the window and type something (no delay)
4. open xterm and type something (like "asdasdasddasddasd" ;-)) you should see a delay
5. then try to move the window
6. do the same with the xfce-terrminal, you will recognize a noticeable delay

this happens only when I use the "--device /dev/dri:/dev/dri"

Cannot replicate, not saying it is not happening to you but I cannot replicate this I get no delay. Also what you are explaining with the stream being permanently lagged is basically impossible as even if you off tab we destroy the entire stream and start it cold when the tab shows again. That is the only action the encoder can take is stop and start and when it stops it is literally unloading everything from memory it is completely flushed and unlike other solutions our framebuffer is external to us to it keeps on going while we wait to read from it again.

What is your latency to this server ?

[hgw77]

There is no latency because I try this with localhost.

I tried to create a screencast to show the problem. When I enter the random characters into the xterm window (this is done with my keyboard in around 2 seconds) you can see to render the whole string in the xterm window needs more time. There it is where the delay begins. Also you can see when I enter the string into the xterm window the mouse pointer is going away and is coming back when the string in the xterm windows is rendered. In that time I can do nothing because I have no mouse pointer. Than I try to move the window und it is following with huge delay the mouse movement.

delay-demo.1.mp4

As a side note, I tried this on relatively old hardware. The screencast above was recorded on an old Lenovo laptop with a Core i5-2540M processor. I also tested it on a workstation with a Core i7-6700.

What I observed is that the effect is much stronger on the older hardware (Core i5-2540M) than on the workstation but it is still disturbing. So perhaps the issue is related to the hardware itself and can be compensated with more modern equipment? However with a fresh started docker container everything runs smoothly and fine until you open Xterm. So in general it is working with the old Hardware as well except this weird issue.

[thelamer]

That processor does not even have avx2 and is from 2011.
See if this works for you
docker run --rm -it --shm-size=1gb --device /dev/dri:/dev/dri -e DRI_NODE=/dev/dri/renderD128 lsiobase/selkies:debianbookworm bash probably won't but worth a try to see if vaapi can be used.
If that i5 is your server you need to temper expectations that processor is basically e waste.

[hgw77]

This is not my server, it is just a free laptop for testing. My server is running with CoreI7 6700. and I can see there the same delay but not that extreme but it is there.

I seems the command above is not complete? I added ports to access it. Is DRI_NODE right, in the documentation it is DRINONE?

docker run --rm -it --shm-size=1gb --device /dev/dri:/dev/dri -e DRI_NODE=/dev/dri/renderD128 -p 3001:3001 lsiobase/selkies:debianbookworm bash

When I logon to https://localhost:3001 I can see a shell. When I type xterm and than do the same as I described above I can see the delay when I enter text.

[thelamer]

Yeah it is a hidden setting vaapi is not ready for mainstream, but it will log like Res: 2560x1280 Mode: H264 (VAAPI) CS_IN:I420 LR FF Stripes: 1 CRF:25 EncFPS: 2.00 EncStripes/s: 2.00

I will make some 2 core mini vm and see what my client looks like though I do not have any old processor to test any of this without current SIMD support.

[thelamer]

Also sidenote on the client it really is on the user to configure the settings for their env, try like jpeg does the same happen with jpeg or stiped modes.
Also 60 fps is not the way with this client, try 30 or 24.

[hgw77]

Got it :-) I played with that options a lot and from client side everything is fine. It works with 60fps and h264 striped and not striped, except I open the Xterm. (I do not use jpeg because this is not that fast)

[thelamer]

"Doctor it hurts when I do this"

Does like chromium playback smoothly? I am just trying to get a gauge outside of dragging around an xterm window. Some kind of baseline.

[hgw77]

I have another hardware configuration that is not working as expected. This is tested on debian bookworm fresh installation, only docker was installed. Than I used for testing the same docker command that I used above (docker run --rm --privileged --device /dev/dri:/dev/dri -p 3001:3001 lscr.io/linuxserver/webtop:debian-xfce-3aab897f-ls136).

Logon to https://localhost:3001 open Xterm and write some random stuff and I can see directly a delay and short after that the mouse pointer disappears. After that it needs some time until the mouse pointer appears again but it is no more possible to click or drag a window. The whole desktop is like frozen and becomes unusable. When I reload the browser window it stays in connecting for long time and when it is coming back it is not possible to use the Desktop because it is the same as before.
