Bug ID: 86038 Summary: [radeonsi] Dreamfall Chapters: heavy visual corruption Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: kai@dev.carbon-project.org
Created attachment 109134 --> https://bugs.freedesktop.org/attachment.cgi?id=109134&action=edit Heavy visual corruption with radeonsi in Dreamfall Chapters
Let me preface this report with the note, that some visual corruption was expected with Dreamfall Chapters on Linux, since there are some broken shaders and the developers are working on fixing those.
With the radeonsi driver (see below for the full graphics stack in use) the visual corrutpion is on the unplayable level, since large parts of the screen are black in certain scenes (it seems to be, when one particular light shader is in use, which also bothers the proprietary driver, but not to this extent). See the attached screenshot for an example how this looks. This is not an Hyper-Z issue, I tried R600_DEBUG=nohyperz to no avail.
For reference I'll also post a screenshot of the same scene with the proprietary driver (which was a PITA to get running, I hate that thing so much), where you can see the difference.
Please let me know, what else you might need to debug this.
