When I launch Kodi, it launches in Windowed mode.
The Kodi window display resolution -- all icons are huge, and the window's expanded way off screen.
I can resize the window, but that doesn't survive restart. It returns to as above.

If I "\" to get to full screen, all looks ok as long as I'm in full screen.
In

Code:
    Settings>Systen>Display

I see

Code:
    General

    Monitor      ---> Default

    Display mode ---> Full Screen

    - Resolution ---> 3490x1964p.

If I click Resolution, the selection dialog opens, displaying only one resolution: 3490x1964p.
Nothing else to select from.

If I click on Whitelist, only one option's available: 3490x1964p 120.00Hz.

I don't know where it's getting that resolution.

How do I get Kodi to detect, or accept change to, the correct resolution for my laptop, i.e., the 1920x1080?

Reminds me of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1031975 : Wayland, windowed mode, and every subsequent Kodi launch doubles the perceived resolution.

Can you check if your config is affected? If yes, we can fix both issues at once!

I run Fedora40 + KDE.

X11 is pretty much a thing of the past here. Well, at least without jumping through a bunch of unsupported hoops ... and I haven't done that.

On exec with x11, fails

Code:
flatpak run tv.kodi.Kodi --windowing=x11

    'this->recurse > 0' failed at ../src/pipewire/thread-loop.c:63 do_unlock()

    ERROR: Unable to create GUI. Exiting

whereas

Code:
flatpak run tv.kodi.Kodi

    'this->recurse > 0' failed at ../src/pipewire/thread-loop.c:63 do_unlock()

    ERROR: Unable to create GUI. Exiting

launches. But has the windowed-size issue.

Checking, in my KDE Display Config, I have

Code:
Resolution: 1920x1080 (16:9)

Scale: 110% <============ fractional scaling ?

Refresh rate: 120 HzAdaptive sync: Automatic

Overscan: 0%

legacy applications (X11):

    [X] Apply scaling themselves

    [ ] Scaled by the system

Reducing the scaling to 100%, on Kodi launch (withOUT the `--windowing=X11`), I still have the windowed-size issue.

@basilgello

and, currently,

Code:
grep -E '\.screen"|\.resolution"|screenmode"|window\.width|window\.height' .var/app/tv.kodi.Kodi/data/userdata/guisettings.xml

    <setting id="window.width">6940</setting>

    <setting id="window.height">3460</setting>

    <setting id="videoscreen.screen" default="true">0</setting>

    <setting id="videoscreen.resolution" default="true">16</setting>

    <setting id="videoscreen.screenmode" default="true">DESKTOP</setting>

Yes, 110% is fractional scaling (aka 1.1). Congrats, you are the second person hitting this bug! Smile

Can you please post the Debug Log with GUI category enabled in the detailed toggle menu?

@basilgello

I don't see a 'GUI category' available -- I enabled "Windowing component".

@basilgello
Is that what you're looking for?

Windowed Kodi growing indefinitely on Wayland will be fixed with this PR: https://github.com/xbmc/xbmc/pull/25955

As for the "wrong" resolution from the tread starter: This in the correct resolution and how scaling on Wayland works. To scale on Wayland (without the fractional scale protocol) works by requesting a smaller window from the application and then the compositor scales it up the intended resolution and making it larger in the process. Because scaling up looks blurry the compositor can instead request the application to render double the size of the smaller resolution (confusing, I know...) and then it's scaled down instead being less blurry. So in OPs case the compositor asked Kodi to render at a logic resolution of 1745x982 but to double the resolution.

If opened in full screen, Kodi spreads between my monitors (Qtile wayland - scaling factor 2). I have to toggle "windowed/full screen" to obtain a full screen Kodi in my primary monitor only. It is the aim of the PR to solve this, am I correct?
