Blender freezes i3wm

Blender freezes i3wm

[Ekaitz Zarraga]

Hi,

I'm recently finding issues running blender. Trying to sculpt a simple shape and rotate the view freezes i3wm but the mouse cursor is still responsive (it even detects when it's on top of a text area or a clickable area) but the screen is frozen and I can open terminals using ctrl-alt-F[2-6] that are actually responsive.

Did you experience anything similar?

I'm on an intel i7-10510U cpu with the integrated graphics card (that is more than capable to handle such models).

Any idea of what can I do to fix this?

Thanks!
Ekaitz

I maaaaay have ran into something similar, but didn't record the exact
error at the time.
What guix commit are you on? And are you using drivers from The
Forbidden Channel?

I've worked on Blender 2.83.9 and Blender 2.91.0 and both had the same issue.

I have to admit that I didn't update the window manager in a while.

And yes, I use the drivers from the forbidden channel.


Were you able to fix the issue?

I haven't used it for a long time in a while, so, not sure. I'll do
some more modeling soon, I'll try to push it then.
I'm using Sway currently, which seems rather stable. Maybe try that?
Don't even need to reconfigure, just guix environment --ad-hoc sway
(and maybe some more packages) and dbus-run-session sway on a different
vtty.

Re: Blender freezes i3wm

Hi all,

I just tried with Gnome Desktop and I was able to replicate the same issue,
it could be related with the hardware or with X11?

I needed to push it a little bit further this time but I remember to
sculpt the models I used for the testing in this actual device or the
previous laptop, which was just older and lower quality...

I am pretty sure this didn't happen in older versions like the 2.7...
:(

The way I manage to replicate is entering the Sculpting mode and rotating
the model.

It just freezes the screen (but not the mouse pointer!).

Just to test I managed to use my muscle memory to run a terminal and
reboot the computer using hotkeys and imagining how should the screen
look like. It actually rebooted the computer as expected.

Also I see no increment on the processing or the temperature of the CPU.

So it's like the window manager or something has issues to manage this
but I don't get what kind of debugging information can I obtain from
the fact that the mouse pointer can be moved around.

Does anyone have any suggestion on that?

I'll give it a try to this too, just in case it's only related with X.

Thanks for the advice. I'll keep you posted!

Btw, I can actually exit the session and stuff like that
but when I'm back it's still frozen.

Does this say something to you?

Does this happen with any blend or just with a particular file? What are the exact steps you follow to enter sculpting mode?

I can try it here to see if I get the same result, but I haven't used Blender in a long time and never did sculpting.

I just tried the following and couldn't reproduce the issue:

1. Start Blender
2. Delete the default cube
3. Add a UV Sphere (Shift+A → Mesh → UV Sphere)
4. Click the Sculpting tab
5. Click and drag on the sphere to sculpt

This is my system info:

OS: Guix System 11488907f793309aec4b7f52f4c155fb2bdd289f x86_64
Kernel: 5.11.7-gnu

I tried to replicate my own issue and I can't.

So it looks like it is solved. I don't know.

Good news then!

Thanks to all for the help and the support!
Much appreciated.

Weirdly enough, yesterday I sculpted for 2h in a row and everything went well.

After that, I opened the model I worked on and it freezed my screen again, but this time some buttons of other screens started to appear on top of the frozen window.

Very weird.

Anyway, this looks like it's impossible to debug so I'm going to act as it didn't happen.

Re: Blender freezes i3wm

I've had the same issue.  I think for me at least, here's the relevant
issue:

  https://developer.blender.org/T72902

Apparently if someone encounters other issues with their card, these
need to be added "on a case per case basis"

  https://developer.blender.org/rBb7acb8690a4d189868c6e0b57057b6fcd8a5a96d

However adding new cards doesn't look too hard.

Not sure if this is too helpful to anyone but I suspect this might keep
happening with intel cards as they roll out.

Spoke too soon, unfortunately. :\

My whole desktop still crashed after some period of use.  However, let
me give some better news...  the patch I linked is not yet in the latest
version of Blender we ship.  So this can probably be fixed either by
upgrading Blender or, should that be annoying to do temporarily, by
backporting this patch, which merges quite cleanly.

Well I was wrong about the patch applying cleanly too.  Not paying close
attention, apparently.  And that patch was merged already in the current
version of Blender we ship.

It looks like my GPU, which is (according to lspci):

  00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake)

has particular trouble:

  https://developer.blender.org/T80458#1182395

Frustrating.

Hi all,

I found this error again and I don't know what to do.
Honestly this sucks really hard.

I checked the error report at blender.org and I find the
same error even with the same file that is added in the error
report:

Is there any chance that we can fix this?
Any ideas?

There's not a fix available upstream yet, right?

I think we have two different versions of Blender. Does the old one work?

There's a mesa suggestion:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/3751
But I didn't try it yet.

It surely will but it lacks most of the features I need :(
