| Summary | Horizontal lines in radeon driver on kernel 3.15 and upwards |
| Product | Mesa |
| Version | git |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | major |
| Priority | medium |
| Component | Drivers/Gallium/r600 |

Created attachment 111292 [details] Youtube video depicting the artefacts. This is what I get if I run any kernel newer than 3.14: https://www.youtube.com/watch?v=nx2-Fvihzxg Those artefacts appear as soon as new kernel is selected in GRUB, and remain after logging into X session. The last kernel working without artefacts is v3.15-rc2-trusty for Ubuntu, and 3.14.7 for Arch. All later kernels have those artefacts. I updated mesa and xorg to those form ppaibaf/graphics-drivers ppa on Ubuntu, and on using git version on Arch but it did not change a thing. This regression is solely kernel-related. GPU: Mobility Radeon HD 3200 (RS780M) System tested: Arch, Ubuntu 14.04, 14.10 Kernels affected: 3.15 and onwards (tested up to 3.19-rc1)
