Description bmilreu 2019-02-22 20:17:31 UTC
Is fixed by this patch https://patchwork.freedesktop.org/patch/285155/ , but it seems to have got forgotten.

@Nicholas Kazlauskas Could you try push this to 5.1?

backported for 5.0 patch

Here's a backported patch for 5.0 Please consider this, anything that doesnt run at maximum vsync fps is a stuttery mess, making Freesync useless (with the fix something like 45-58fps is smooth, tearless and stutter free which is what VRR is supposed to do).

Fix was pushed to 5.0, should we mark this as resolved for now?

You're the reporter, if you consider it resolved, please mark it as such.

It technically isn't in amd-staging-drm-next directly yet, but it is in the fixes branch. It'll make its way to staging and 5.1 eventually.

Like Michel said, feel free to mark as resolved when you feel that it is.
