After doing the recently stabilized KDE/Plasma updates, i get strange rendering errors. in particular in the top/left top/right bottom/left bottom/right corners i can see fragments of other application windows - which clearly shouldnt be the case :) i already updated xorg and drivers as suggested here: https://bugs.gentoo.org/show_bug.cgi?id=572868 but that didnt help (i also have intel-hd graphics). installed packages that might be relevant: /var/db/pkg/kde-apps/plasma-runtime-15.08.3/plasma-runtime-15.08.3.ebuild /var/db/pkg/kde-frameworks/plasma-5.18.0/plasma-5.18.0.ebuild /var/db/pkg/kde-plasma/kde-cli-tools-5.5.5/kde-cli-tools-5.5.5.ebuild /var/db/pkg/kde-plasma/kde-gtk-config-5.5.5/kde-gtk-config-5.5.5.ebuild /var/db/pkg/kde-plasma/kdecoration-5.5.5/kdecoration-5.5.5.ebuild /var/db/pkg/kde-plasma/kdeplasma-addons-5.5.5/kdeplasma-addons-5.5.5.ebuild /var/db/pkg/kde-plasma/kscreen-5.5.5/kscreen-5.5.5.ebuild /var/db/pkg/kde-plasma/kscreenlocker-5.5.5/kscreenlocker-5.5.5.ebuild /var/db/pkg/kde-plasma/libkscreen-5.5.5/libkscreen-5.5.5.ebuild /var/db/pkg/kde-plasma/plasma-desktop-5.5.5/plasma-desktop-5.5.5.ebuild /var/db/pkg/kde-plasma/plasma-meta-5.5.5/plasma-meta-5.5.5.ebuild /var/db/pkg/kde-plasma/plasma-pa-5.5.5/plasma-pa-5.5.5.ebuild /var/db/pkg/kde-plasma/plasma-workspace-5.5.5-r2/plasma-workspace-5.5.5-r2.ebuild /var/db/pkg/kde-plasma/sddm-kcm-5.5.5/sddm-kcm-5.5.5.ebuild
fwiw, current stable xf86-video-intel works very well on my system, but it's been really hit-and-miss depending on your combination of hardware and software versions with Intel lately... That is: x11-drivers/xf86-video-intel-2.99.917-r2 x11-base/xorg-server-1.17.4 Doesn't limit me to an old kernel though, I'm running 4.5.0 gentoo-sources at the same time.
Please list the versions of kernel, xorg-server and xf86-video-intel that you have installed.
kernel 3.18.11-gentoo #1 SMP (yeah a bit old, i will upgrade as soon as i find the time...) xorg-server-1.17.4 xf86-video-intel-2.99.917-r2
forgot: i had the same problem with earlier versions of xorg-server and xf86-video-intel (thats why i upgraded, these are non stable on amd64)
Running modern xf86-video-intel with old kernel is known to cause problems. Please use latest stable or latest unstable versions of both.
as said, i had the problems before, and only upgraded to the unstable versions because the above mentioned bug suggested it might fix it (it didnt). i am sure downgrading again will not fix it either for that matter :)
Use either gentoo-sources-4.1.15-r1 xorg-server-1.17.4 xf86-video-intel-2.99.917-r2 or gentoo-sources-4.5.0-r1 xorg-server-1.18.3 xf86-video-intel-2.99.917_p20160410 You can try with older kernels, but in that case you may also have to downgrade xf86-video-intel further to 2.21.15
ok, so, upgraded kernel, downgraded xorg and drivers: gentoo-sources-4.1.15-r1 xorg-server-1.17.4 xorg-drivers-1.17 xf86-video-intel-2.99.917-r2 ...still the same issue :( (if that matters, my desktop resolution is 1600x1200, using one screen only)
maybe this helps, this is the lspci -v output for the GFX "chip" (integrated into CPU) 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller]) Subsystem: ASRock Incorporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 28 Memory at f7800000 (64-bit, non-prefetchable) [size=4M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 Kernel modules: i915
After upgrading to kernel 4.6.2 and KDE Plasma 5.6.5, I have no issues with Intel graphics anymore. Perhaps you should try that combination too?
I have a similar problem as of July 2017. See bug report 590894 (see the screenshot attachment there). I am running gentoo-sources-4.4.6-gentoo x11-drivers/xf86-video-intel-2.99.917-r2 x11-base/xorg-server-1.17.4 x11-base/xorg-drivers-1.17 kde-plasma/plasma-meta-5.6.5 These packages are the ones in the stable tree as of 2016-08-12. My graphics HW is Intel HD Graphics 5500 Can anyone confirm that the above combination gives the problems mentioned in this bug report and in bug report 590894?
On my parents computer I saw graphical issues, then upgraded kernel to 4.6.X and problems went away. Everything else is installed as a stable version. Have you tried a newer kernel?
finally found some time for updating my desktop.... the problem is still there, using these (stable system): gentoo-sources-4.4.26 xf86-video-intel-2.99.917_p20160621-r1 xorg-server-1.18.4 xorg-drivers-1.18-r1 plasma-meta-5.8.3
We have zero ability to solve problems like this. Please file a bug upstream: https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/intel Two suggestions: Try the 2.99.917_p20161206 unstable version of xf86-video-intel Try a 4.9.x series kernel
> Try the 2.99.917_p20161206 unstable version of xf86-video-intel > Try a 4.9.x series kernel just for the records: none of that changes anything :(
By the way, I suggest anyone having trouble with the Intel driver try dropping it and using modesetting instead. This is the default now in some major distributions, is recommended by KDE upstream, and is working well personally for me.
exactly the same problem with modesetting here :(
