In addition to working on sharply improving the performance of Deus Ex: Mankind Divided when using the RadeonSI Gallium3D driver, Marek Olšák has published some patches for improving The Witcher 2 with the open-source AMD driver stack.

The Witcher 2 has been out for Linux since 2014 while coming now is a workaround for Witcher 2 having some black transitions when using the RadeonSI Gallium3D driver.

The Witcher 2 black transition fix comes via this patch series. But as one of the code comments mention, the underlying issue still isn't clear, "This must be 1 for Witcher 2 to render correctly. The cause of the Witcher 2 issue is still unknown. I only know that M0 is correct throughout the whole shader."

Witcher 2 black issues with RadeonSI appear to date back at least months for those playing this action role-playing hack and slash video game on the open-source AMD driver code.

In other work, Marek also corrected today a potential hang with RadeonSI.
