Wlroots: Segfault with latest egl context change

[J0nnyMak0]

With https://github.com/swaywm/wlroots/commit/1edc42157bbb01b25ec27750f883fd84ee5908d6 I'm getting a segfault at startup.

Can you try https://github.com/swaywm/wlroots/pull/2210?

[J0nnyMak0]

That is hanging. I'll try to get info from log.

Log attached.

On exit, I get:
[backend/drm/atomic.c:36] eDP-1: Atomic commit failed (modset): Permission deniedl page-flip failed

[emersion]

Abort fixed, but there's still this eglSwapBuffers failure to address.

I'm seeing the eglSwapBuffers failure and hang on latest master as well. Using a single GPU (Intel Haswell integrated graphics), kernel 5.6.13. Reverting commit d28a7da95d1a ("backend/drm: add missing wlr_egl_unset_current") gets rid of the problem for me.

Can you try https://github.com/swaywm/wlroots/pull/2212?

Can you try #2212?

It's fixed here with #2212.

[emersion]

I've actually come up with a Better(tm) solution, can you try https://github.com/swaywm/wlroots/pull/2213?

[hensur]

I just ran into this as well. I didn't try #2212, but I can report that #2213 fixes the issue for me.

[deprecated-dot]

Same issue on my end, log has similar failings and #2213 fixes it. Dual GPU setup (R9 Fury X + RX 5700 XT - both AMDGPU), Gentoo. Wanted to leave a comment so that there's confirmation from more than one person that #2213 fixes it.

Another confirmation: #2213 fixes the issue for me.
