Created attachment 399024 [details] emerge.info Hi, not sure when this issue started to happen, however, as the title says i'm having some rather annoying graphical bug where usually the chrome and sometimes the whole window is full of graphics artifacts as shown in the attachment. some additional infos: libdrm-2.4.59 (libkms -static-libs ABI_MIPS="-n32 -n64 -o32" ABI_PPC="-32 -64" ABI_S390="-32 -64" ABI_X86="64 -32 -x32" VIDEO_CARDS="radeon -exynos -freedreno -intel -nouveau -omap -tegra -vmware") xf86-video-ati-7.5.0 (glamor udev) 1.17.1-r1 (ipv6 nptl suid udev xorg -dmx -doc -glamor -kdrive -minimal -selinux -static-libs -systemd -tslib -unwind -wayland -xephyr -xnest -xvfb) X11 config ---------- Section "Monitor" Identifier "Monitor0" VendorName "IIYAMA" ModelName "IIYAMA B1906S" EndSection Section "Device" ### Available Driver options are:- ### Values: <i>: integer, <f>: float, <bool>: "True"/"False", ### <string>: "String", <freq>: "<f> Hz/kHz/MHz" ### [arg]: arg optional #Option "NoAccel" # [<bool>] #Option "SWcursor" # [<bool>] #Option "Dac6Bit" # [<bool>] #Option "Dac8Bit" # [<bool>] #Option "BusType" # [<str>] #Option "CPPIOMode" # [<bool>] #Option "CPusecTimeout" # <i> #Option "AGPMode" # <i> #Option "AGPFastWrite" # [<bool>] #Option "AGPSize" # <i> #Option "GARTSize" # <i> #Option "RingSize" # <i> #Option "BufferSize" # <i> #Option "EnableDepthMoves" # [<bool>] #Option "EnablePageFlip" # [<bool>] #Option "NoBackBuffer" # [<bool>] #Option "DMAForXv" # [<bool>] #Option "FBTexPercent" # <i> #Option "DepthBits" # <i> #Option "PCIAPERSize" # <i> #Option "AccelDFS" # [<bool>] #Option "IgnoreEDID" # [<bool>] #Option "DisplayPriority" # [<str>] #Option "PanelSize" # [<str>] #Option "ForceMinDotClock" # <freq> # Option "ColorTiling" "true" # [<bool>] #Option "VideoKey" # <i> #Option "RageTheatreCrystal" # <i> #Option "RageTheatreTunerPort" # <i> #Option "RageTheatreCompositePort" # <i> #Option "RageTheatreSVideoPort" # <i> #Option "TunerType" # <i> #Option "RageTheatreMicrocPath" # <str> #Option "RageTheatreMicrocType" # <str> #Option "ScalerWidth" # <i> # Option "RenderAccel" "true" # [<bool>] #Option "SubPixelOrder" # [<str>] #Option "ShowCache" # [<bool>] #Option "DynamicClocks" # [<bool>] #Option "VGAAccess" # [<bool>] #Option "ReverseDDC" # [<bool>] #Option "LVDSProbePLL" # [<bool>] # Option "AccelMethod" "EXA" # <str> #Option "DRI" # [<bool>] #Option "ConnectorTable" # <str> #Option "DefaultConnectorTable" # [<bool>] #Option "DefaultTMDSPLL" # [<bool>] #Option "TVDACLoadDetect" # [<bool>] #Option "ForceTVOut" # [<bool>] #Option "TVStandard" # <str> #Option "IgnoreLidStatus" # [<bool>] #Option "DefaultTVDACAdj" # [<bool>] #Option "Int10" # [<bool>] #Option "EXAVSync" # [<bool>] #Option "ATOMTVOut" # [<bool>] #Option "R4xxATOM" # [<bool>] Identifier "Card0" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "RV770 [Radeon R9 290]" # BusID "PCI:1:0:0" EndSection #Section "Screen" # Identifier "Screen0" # Device "Card0" # Monitor "Monitor0" # SubSection "Display" # Depth 1 # EndSubSection # SubSection "Display" # Depth 4 # EndSubSection # SubSection "Display" # Depth 8 # EndSubSection # SubSection "Display" # Depth 15 # EndSubSection # SubSection "Display" # Depth 16 # EndSubSection # SubSection "Display" # Depth 24 # EndSubSection #EndSection thanks in advance

Which graphics chipset is this? Does switching between EXA and glamor make a difference, or switching between raster and native Qt graphics system?
it's ATI Radeon R9 290, and no it didn't make any difference. What i tried is eselect qtgraphicssystem set 2 -- opengl, didn't work at all, then eselect qtgraphicssystem set 3 -- raster (default), didn't fix the bug then i switched the AccelMethod setting from EXA to glamor, no difference.
As radeonsi cards use only glamor, switching to EXA does not have any effect. Try upgrading xorg packages to latest unstable versions, namely eselect-opengl-1.3.1-r4 glproto-1.4.17-r1 mesa-10.5.1 llvm-3.6.0 xorg-server-1.17.1-r1 If you have the stable version of emul-linux-x86-opengl installed, you may also need to upgrade it to 20140508-r1 to avoid blockers.
That's actually all the versions i have installed on my box anyway.
Does this happen in only KDE/Qt applications, or in other toolkits too?
Seems to be in Qt Apps only, as i don't have the artifacts in Gimp, nor in Vivaldi.
does this still happen on an up-to-date system?
If you can still reproduce, please file a bug upstream.
