Generic LE13 nightly (20260529) video issue with N100

    Hi, I love the direction LE is taking and I have been hoping for this for a long time. I am currently running this on an AMD box and so far no issues. I thought I would swap to a small N100 NUC and it mostly works. The N100 seems to have an issue changing resolution. Its connected to an AVR -> TV and after install it boots into 4K resolution. I can play all my media no issue. I also love being able to use a web browser (firefox) for netflix and prime content. This works fine to.

    This is until I try and drop Kodi resolution to 1080P then the screen turns to static, I leave it to auto return to 4k and the picture returns. Also I dont really want the web browser in 4k either so dropping that to 1080P has the same result, screen is static. I just use the mouse to top right and corner and click which hopefully shuts the browser down and if I get it right Kodi will once again reappear in 4k.

    Is this a me only issue?

    Nobody else has reported anything similar and I'm not seeing anything on an N150 box. Some major changes were merged around 11th May so we are interested to know if a nightly from the first week of May (before them) results in a different experience? You should also ensure the N100 device is running the latest BIOS and LSPCON firmware; most devices will need to run update tools under Windows which can be inconvenient, but it can be important. Also provide the output from "pastekodi" with Kodi in debug mode with bug reports so we can see what's actually happening and/or look for interesting error messages.

    I did some testing, I am using a MeLE Quieter 4C N100, latest BIOS. It does not have an LSPCON chip inside, /sys/class/drm shows HDMI connectors and dmesg doe not list the device.

    I have found this issue only happens when plugged into the AVR, directly into the TV it works OK.

    One thing that is interesting is the TV is reporting the signal is 1080P@62 htz when the screen image is garbled. I also tried getedid create in case of it being a edid issue but no luck.

    I installed version 20260505, I am able to change resolution of Kodi with this version without problems but cannot test a flatpak app as its not available.

    I will re-install the newest version again and see what logs I can get

    I have logs,

    So today I noticed when I have the browser open with the resolution in Flatpak set to 1080P and screen is garbled, moving mouse to top right hand corner to close, kodi was restarting up garbled as well, but if I unplug and re-plug of the HDMI lead gives me the correct image at 1080P60.

    kodi.log.old as after boot and display is ok.

    kodi.log is after firefox has closed and screen is garbled

    When I open the browser if I pull the HDMI and plug back in the display comes right but at 4k resolution.

    Can you please test with the 20260511 and 20260512 nightlies and report back if resolution switching works with those?

    I have a gut feeling that the issue might be caused by the Intel hack-patch that was added in the 20260512 nightly.

    If you get the garbled screen in both nightlies please test with earlier nightlies between 20260504 and 20260511 and post the first version where the issue occurs.

    so long,

    Hias

    I ran the tests tonight, they both had the same result, loading up firefox in 1080P has issues. I will try some more previous versions another day. I will start at 20260504
