Comment # 14
on bug 98520
from Itzamna
I would like to confirm this bug. Since a world update yesterday, 3D acceleration has become unusable due to random freezes. Just like MirceaKitsune, I am running on KDE (Plasma 5.8.3) and am on a rolling release distribution (Gentoo). I have tried several kernel, Mesa and libdrm versions, but the freezes prevail. After a freeze occurs, I can SSH into my system and it is otherwise responsive; except for being unable to kill the X server or display manager (sddm). Switching KWin's rendering path to XRender prevents hangs from occurring when on the desktop; the OpenGL 3.3 and 2.0 rendering paths will provoke hangs. When my system hangs, dmesg shows no related messages at all; Xorg.0.log shows nothing out of the ordinary either. Any suggestions on how to obtain useful debugging information is welcomed. My system information is as follows: Linux kernel version: 4.9.0 Mesa version: 13.0.2 LLVM version: 3.9.0-rc1 libdrm version: 2.4.76 Video card: RX 460 4GB Processor: Intel Core i7-5775C
