Priority: medium Bug ID: 59015 Assignee: dri-devel@lists.freedesktop.org Summary: Steam Beta: Graphical Corruption in certain parts of application tied to "kernel rejected CS" messages Severity: major Classification: Unclassified OS: Linux (All) Reporter: adam.jorgensen.za@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: 9.0 Component: Drivers/Gallium/radeonsi Product: Mesa
Created attachment 72495 --> https://bugs.freedesktop.org/attachment.cgi?id=72495&action=edit Major Graphical Corruption Occurring in Windows that are not Maximised
I am participating in the Steam Linux Beta and am experiencing graphical corruption as captured in the screenshots attached to this ticket.
By starting Steam from the command-line I was able to observe logging messages and noticed that every time a graphical corruption artifact occurs the application outputs the message:
"radeon: The kernel rejected CS, see dmesg for more information."
An examination of dmesg reveals messages as follows:
" [ 2491.179581] radeon 0000:02:00.0: r600_cs_track_validate_cb invalid tiling 6 for 0 (0x08110668) [ 2491.179588] radeon 0000:02:00.0: r600_packet3_check:1913 invalid cmd stream 566 [ 2491.179592] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream ! "
