Comment 3 schrott3000 2015-03-31 06:02:37 UTC

Try 4.0.0-rc6, should be fixed there. I have reported a different aspect of this in Bug 95541 and noticed that at least my bug disappeared in 4.0.0-rc6.

Comment 4 Jani Nikula 2015-10-07 10:09:02 UTC

Long time no updates, closing.

If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you.
