CCS: GUI Flickers on mouse Movement after web content was shown

Other Parts Discussed in Thread: CCSTUDIO

Tool/software: Code Composer Studio


I'm experiencing enormous flickering when of the UI in CCS Version: on Linux, Ubuntu 18.04 LTS with KDE as DE.
The UI flickers rapidly when the mouse cursor in moved, and in about 1 Hz when the mouse cursor stays still.

It happens when I open the ROV or the Resource Explorer. In the resource explorer less quickly, in the ROV usually after clicking 1-3 elements.

The ROV or Resource explorer don't flicker, but the rest of the UI does.

If you need any more details, let me know.

  • Hello Johannes,

    Can you try the below workaround:

    Open a terminal and type:

    > export SWT_GTK3

    then (in the terminal), browse to <CCS9 INSTALL DIR>/ccs/eclipse and run ./ccstudio

    Check to see if the issue still exists or not.



  • Hello Johannes,

    Just following up with you to see if you had a chance to try the proposed workaround



  • Hi Ki,

    with setting eclipse to use GTK3, the ROV seems to work normally and does not introduce flickering anymore. The Resource explorer on the other hand still makes the GUI flicker.

    But having the ROV working already helps me a lot. I can open the resource explorer in the browser as well.

    Thank you very much already!



  • Actually, I meant to say:

    > export SWT_GTK3=0

    I forgot the part about explicitly setting it to 0. But I think both ways do the same thing. At least that is the behavior I see.

    I'm not sure why the workaround works for ROV but not ReX. It should apply to both.

    I filed a bug for the flicker issue. Tracking ID: CCDSK-3753
