Description Michel Dänzer 2017-01-26 09:48:16 UTC

If DRM_IOCTL_MODE_PAGE_FLIP fails for a client buffer, the screen freezes.

What should probably happen is that weston falls back to compositing instead of directly displaying the client buffer.

It's doable but infuriatingly difficult; I'd honestly rather just try to migrate people to atomic, and remove fullscreen bypass for non-atomic ...

Works for me. :)

Marking as a duplicate of #96841, which notes the same fundamental issue and talks about how to recover from it.
