There are some news on the $Subject: [1]. (have a look at the chapter "Fine tuned")
I thought it could help Wine fixing such bugs as 6086, 13085, 17260, 22362 [2].
I'll paste the text in just for archiving purposes:
--- quote --- Fine tuned
The kernel hackers have extended the DRM infrastructure to include "precision vblank timestamps", which are explained in detail in the commit comment and are relevant to OpenML (Open Media Library) conformity. This feature enables the kernel to provide timestamps with an accuracy of a few microseconds, allowing applications to detect when the rendering of a new image has started ("double-buffer swap"). This can, for instance, be relevant for applications where it is important to precisely co-ordinate the audio output, or the control of other devices, with the rendering of the image. The technology was first implemented for experimental psychology and neuroscience applications, but it can also be applied to provide (more) jerk-free video playback, animations or desktop effects.
Such timestamps can also be utilised by the new page flipping feature available via DRI2. This feature improves the way the kernel synchronises the release of an updated image with the moment the graphics hardware starts rendering the new image (Vsync). Synchronising the release avoids such distortions as flickering, tearing or incomplete rendering, as it prevents situations where one half of a displayed image is part of the old image while the other half is part of the new image . for instance with individual movie frames. In kernel version 38, the graphics driver support required for both features will be available via the AMD drivers (1, 2) and the Intel drivers (1, 2). The NVIDIA drivers currently only support page flipping (1, 2). --- quote ---
