Radeon HD 7730 graphical artifacts (open source driver)

Hi,
I'm not very familiar with AMD video cards, so I hope there's someone with more knowledge on this topic, who can help me with this issue.
With no xorg configuration I get this artifacts after X starts (same in KDM):

With custom 20-radeon.conf (provided down below) I'm able to get rid of the artifacts but OpenGL compositing in KDE doesn't work:

Same issue in wayland:

Here's some info and logs:
20-radeon.conf

Re: Radeon HD 7730 graphical artifacts (open source driver)

Check out the manpage, there are more options you can play with. Does that help?

Re: Radeon HD 7730 graphical artifacts (open source driver)

Rexilion,
The only usable config is this (with disabled hardware acceleration). None of the other options helped:

Section "Module"
    Load "dri2"
    Load "glamoregl" 
EndSection


Section "Device"
    Identifier "Radeon HD 7730/8730"
    Driver "radeon"
                                          # default value:
    Option "AccelMethod"       "glamor"   # glamor or EXA
    Option "SWcursor"          "off"      # off
    Option "NoAccel"           "on"       # off
#    Option "ZaphodHeads"       "DVI-0"    # "LVDS,VGA-0"
    Option "ColorTiling"       "on"       # on
    Option "ColorTiling2D"     "on"       # on
    Option "EnablePageFlip"    "on"       # on
#    Option "AccelDFS"          "off"      # wiki fix for artifacts upon logging in (desn't work)
# EXA specific:
#    Option "EXAVSync"          "on"       # off
#    Option "EXAPixmaps"        "on"       # on with > 32MB VRAM
#    Option "SwapbuffersWait"   "on"       # on
EndSection

Any other ideas?

Re: Radeon HD 7730 graphical artifacts (open source driver)

Question: You have 3d accel disabled, why? You mentioned it's enough to flip the accelmethod to prevent the artifacts.

Re: Radeon HD 7730 graphical artifacts (open source driver)

Rexilion,
I switched to this config, but it still looks the same as glamor with no accel:

#Section "Module"
#    Load "dri2"
#    Load "glamoregl" 
#EndSection


Section "Device"
    Identifier "Radeon HD 7730/8730"
    Driver "radeon"
                                          # default value:
    Option "AccelMethod"       "EXA"      # glamor or EXA
    Option "SWcursor"          "off"      # off
    Option "NoAccel"           "off"      # off
#    Option "ZaphodHeads"       "DVI-0"    # "LVDS,VGA-0"
    Option "ColorTiling"       "on"       # on
    Option "ColorTiling2D"     "on"       # on
    Option "EnablePageFlip"    "on"       # on
#    Option "AccelDFS"          "off"      # wiki fix for artifacts upon logging in (desn't work)
# EXA specific:
    Option "EXAVSync"          "on"       # off
    Option "EXAPixmaps"        "on"       # on with > 32MB VRAM
    Option "SwapbuffersWait"   "on"       # on
EndSection

1: glamor with  Option "NoAccel" "off" - artifacts
2: glamor with  Option "NoAccel" "on" - no artifacts
3: EXA with  Option "NoAccel" "on/off" - no artifacts
But with 2 and 3 OpenGL compositing in KDE doesn't work (resets itself to XRender), and graphics in supertuxkart looks like this.

Re: Radeon HD 7730 graphical artifacts (open source driver)

Mah0,
have you tried running with radeon.dpm=1 added to your kernel boot line ?
(While it's default on for most cards, it's disabled for some)

Also development of the radeonsi driver for your card goes fast, have you tried running a mesa git version to see if that improves the artifacts ?

Lone_Wolf,
Unfortunately, no luck with radeon.dpm=1.
I'll try to build mesa-git later.
Thanks.

Re: Radeon HD 7730 graphical artifacts (open source driver)

Shouldn't it be

radeon.dpm=0

to disable the troubled dpm?

Re: Radeon HD 7730 graphical artifacts (open source driver)

Lone_Wolf,
Updating to mesa-git, mesa-libgl-git, ati-dri-git and glamor-egl-git didn't do anything.
Rexilion,
neither of them helped.

I guess I should try my luck with catalyst.
Thanks for all your help guys!

EDIT:
Catalyst works quite well so far

Re: Radeon HD 7730 graphical artifacts (open source driver)

I'm sorry to bump this but I've filed a bug on FreeDesktop (https://bugs.freedesktop.org/show_bug.cgi?id=79231). I'm suffering from this on my Fedora box too... Should you have any extra info about this, feel free to add it to the bug report.

Re: Radeon HD 7730 graphical artifacts (open source driver)

There seems to be a fix available now. This patch requires a slight modification which works perfectly for me. Everything is available in a bug report.
