Hello everybody, and let me say thank you for your help.
What is the problem?
I noticed that, recording the screen with SimpleScreenRecorder, will produce videos with flickering. Also, if I disable the desktop effects and enable it again, and then, open Dolphin or system settings, hovering the mouse over any control will cause the screen to flicker, showing black spaces intermittently.
What have I tried?
- Use UXA as accel method on 20-intel.conf. This is the actual file:
#/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
Option "DRI" "3"
EndSection
- Use OpenGL 3.1 and Full Screen repaints for VSync, and Accurate scale method.
- Some people suggets to use GLX as OpenGL interface, but I can't find that option in System Settings.
- Use OpenGL 2.0
- Disable desktop effects and enable again.
What have worked?
- Scale Method: Smooth(slower)
- Rendering Backend: XRender
- Tearing prevention: Automatic
However, effects like Blur and Wobbly Windows get disabled. Also, the vertical Sync is affected, so, when you move a window fast, you can notice the screen refresh. I'm looking for a real solution for this, I mean, no flickering with OpenGL.
System information:
Plasma version: 5.9.1
KDE Framework version: 5.30.0
QT Version: 5.8
Kernel Version: 4.9.8-1-ARCH
OS Type: 64-bit
Video driver: x86-video-intel
Thanks in advance.

Remove that 20-intel.conf and xf86-video-intel, it is known to break KDE effects and largely unmaintained, and mostly the xorg built-in modesetting driver should be preferred in this case.

Hello!, Thanks for your advise. I have uninstalled xf86-video-intel, and removed the 20-intel.conf file. Then rebooted. However, the problem is still present. I forgot to mention that, I also have
mesa-libgl
, and
lib32-mesa-libgl
installed.

export KWIN_USE_BUFFER_AGE=0
export KWIN_PERSISTENT_VBO=0
kwin_x11 --replace &
One of the variables is likely unneeded (so figure which it is, if this works)

Thanks, I tried it, but no luck. However, the animation speed is improved a little, but, when maximizing windows, the tittle bar dissapears, or only the half is shown.
