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.

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.

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

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!
