sway/wlroots hang with nouveau spam in logs after upgrade

[awly]

After upgrading sway from 1.6 to 1.6.1 and wlroots from 1.13.0 to 1.14.0, I'm getting nouveau error spam in dmesg. It happens after sway starts and I launch firefox:

2021-06-28T07:58:21.121808-07:00 localhost kernel: [  126.779168] nouveau 0000:01:00.0: DRM: bo 0000000019986f93 pinned elsewhere: 0x00000001 vs 0x00000002

After that everything just hangs, although responds to input (I can blindly type swaymsg exit).

WLR_DRM_NO_MODIFIERS=1 is set. Kernel version 5.12.12_1
Prior to the package upgrade, everything worked as expected.

Attached debug log.

In wlroots logs:

In dmesg:

I am experiencing the same issue. I went through a git bisect session since last working version (0.13), the commit that is introducing the regression is: 6c3d080.

[fwsmit]

That commit is about the cursor. That would make sense to me, since for me it seemed to appear after the cursor image was changed.

[emersion]

Can you try #3021?

[mpsq]

@emersion I can confirm that #3021 fixes the issue (writing this very comment from ff on an external monitor with nouveau, your branch runs smoothly overall).

Thanks for fixing this so quickly 👍

[fwsmit]

I've confirmed it works as well 👍

Fixed for me as well, thank you very much!
