Please open the calibration window, and then (without closing it) run
> kscreen-doctor -o
and attach the output of that here.
Hi Xaver,

*** Bug 504387 has been marked as a duplicate of this bug. *** That looks correct. Let's see if the app shows the surfaces correctly. Please start it with
> WAYLAND_DEBUG=1 hdrcalibrator DP-3
move the slider a bit, and then just close it again.
If you attach the output of that here, we should hopefully see the problem.
Also, what icon theme are you using?

Hi, ive attached you the log. Created attachment 181513 [details]
Jonathan's hdrcalabration log
This tested on a RTX 4080. I am using a different icon theme and its icon stands out more than the breeze one on my system. Slider doesn't do anything.
*** Bug 504383 has been marked as a duplicate of this bug. *** The wayland debug log also looks correct. To be honest, I'm out of ideas here :/ When I start the calibration I see a short flicker of the logo, which is then replaced by the white box, only. As an update, this only seems to happen on NVidia. Somehow, QWindow::requestUpdate never actually triggers a commit on NVidia, so the brightness of the icon never gets updated. A possibly relevant merge request was started @ https://invent.kde.org/plasma/kscreen/-/merge_requests/380 Hi, I have rebuild kscreen from latest -git commit and patched the 390 MR over. The Logo/Brightness does now adjust properly, but in the second Callibration step the house image was not present and just black (In reply to Peter Jung from comment #13) > Hi, > > I have rebuild kscreen from latest -git commit and patched the 390 MR over. > The Logo/Brightness does now adjust properly, but in the second Callibration > step the house image was not present and just black Do you have kimageformats installed? If not, the image won't show (in 6.4 branch it still uses a png to avoid that) Thank you Xaver - installing kimageformats have fixed this issue! Thanks for your fast fix!
