Bug ID: 104306
Summary: Mesa 17.3 breaks Firefox and other Xwayland apps on
AMD HD7750
Product: Mesa
Version: 17.3
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: mesabu...@p33.org
QA Contact: dri-devel@lists.freedesktop.org
On latest stable Archlinux with AMD HD7750, Mesa 17.3 breaks Firefox,
Libreoffice, mpv with X11 backend and Chromium (when running WebGL).
Launching firefox or glxinfo from command line results in no response and no
crashes. There are no errors in dmesg or journalctl, except Probe failed with
amdkfd, but blacklisting amdkfd doesn't solve the issue. Using strace on
firefox there are system interrupted notices. Chromium works, but opening any
WebGL page freezes Chromium. mpv with X11 backend shows Bad Drawable, server
failed to allocate resource.
Downgrading to mesa 17.2.6 solves the issue.
