Screen flickering issue

Solved

Hello, I just installed Fedora 24 on an old Asus X61Z. The problem is as follows: whenever the PC needs to display animations, put a window in full screen, or change sessions (basically, every time significant graphical processing is required), the image starts to flicker for a few seconds. I think this issue arises from an incompatibility with the open-source driver. Since I'm new to Linux, could you guide me on how I can resolve this issue?

Thank you

Configuration: Linux / Chrome 52.0.2743.116

    Hello,

    In my opinion, it's the driver for your graphics card that isn't right. You need to tell us which model of card it is (to find out, type 
    lspci | grep VGA
    in a terminal and copy-paste the result).

    A simple solution is to disable desktop effects (3D effects). Let us know which environment you are using (KDE plasma, GNOME, ....) if you want more details.

    Good luck.

      Thank you for responding quickly. Indeed, I had come to the same conclusion as you. I don't have the PC in question on hand, but I can quickly provide this information from memory:
      after running an lspci, it tells me that my graphics card is a VGA compatible device from AMD RS780M, which is a Radeon HD 3200.
      In terms of the environment, I am using Plasma.
      Thank you.
      P.S.: I was unable to install the ATI Catalyst legacy driver.

    Hello,

    Indeed, Radeon cards can sometimes be a bit difficult under Linux... Well, you can always try a driver provided here, but...
    http://support.amd.com/en-us/download/linux

    If it still doesn't work, the simplest thing is to disable desktop effects. In KDE Plasma, go to 
    K > Display and Monitoring > Compositor
    and there you uncheck "Enable desktop effects on startup".

    At any time you can toggle the effects on/off with the shortcut alt shift f12. If you have any transparent areas (for example, your Konsole if you've chosen a translucent style, or your KDE panel if it is translucent), these will become opaque, which will indicate whether the effects are active or not.

    Good luck!
