    Did you try this?

    Maybe also with fb0?

    I don' see the IPU warnings as an acute issue. These may occur on high system load and maybe loading both displays causes a lot of load.

    In my console output shared before, I noticed:

    After some investigation, I come to the conclusion, that clone mode is not stable on this hardware with fbdev.

    Would you also relate to this?

    What PIX_FMT and DATA_WIDTH is your Diplay using?
    https://github.com/FSEmbedded/…ts/F%2BS/efusa9dl.dts#L77

    Is it RGB or BGR? The color seems to change from Yellow to turquoise.
    This suggests that the red and blue channels are swapped.

    Hello,

    Yes. Before starting any weston instance, I unblanked fb2. The application on LVDS remains blurry rendered with color shifts.

    I have attached the console output, when starting Weston in two instances in clone-mode and starting my GUI app.

    Hello,

    we did not notice any color change, when enabling the clone-mode on any display.
    However, I thing it is important to unblank the HDMI display before starting weston with the clone mode.
    Is this done correctly?

    Hi,

    thanks for your answer. It works.

    However, I experience false colors of the application rendered on the LVDS screen, as soon as I unblank fb2/ clone to the second weston instance on HDMI.

    The colors on HDMI are correct, whatsoever. Feel free to check…

    Hello,

    please test the following:

    Set fb0 to lvds and fb1 to hdmi in your device tree
    (Code, 2 lines)


    Boot your board and run the following commands:
    (Code, 3 lines)


    This should open a weston instance, that mirrors the framebuffer from /dev/fb0 to /dev/fb1.
