    Thank you.
    Running the linked openSUSE TW version.
    Can't say for sure if it helps.
    Any special tests/sites (vsync)?

    I would like to know what is improved with that kwin-lowlatency patches, as I'm using Plasma in an Intel APU and it works flawlessly.

    One question: ┬┐does any of you knows if you can have different fractional scaling on different screens?

    Exactly these changes where reverted before the 5.18 code freeze, so you likely fell victim of placebo.

    Hello @tildearrow,

    can you please resend your KWin-lowlatency repro?
    Besides that I compiled KDE last around 1998/1999 (!!!) I've more than interested.
    Maybe I can invite the openSUSE TW maintainer...
    Good job!

    The whole experience has been terrible under Wayland: it scales the UI worse than on Xorg, Chromium is blurry, Firefox does not work (or it's blurry on XWayland), vscode is blurry. The softwares I spend 99% of my time on simply don't work well enough. Of course I could compile chromium-ozone and electron-ozone, but considering Firefox didn't work on Wayland I fear it would be a waste of time. Especially because even Plasma applications like the system settings started to corrupt the font rendering after a while. It's simply not worth it right now, unless you desperately need per-screen scaling.
    With my Vega 8 on my 3500U and my desktop's RX 590, i have had no issues with the fractional scaling on Wayland. I don't personally use integer scales. Does it look clear with a fractional value? Might want to make a bug report.

    They will never, ever merge full-screen unredirection... plus you'll know more about it later

    Hm, I'm not sure whether it's KDE or Arch, but for me the night light widget does nothing. I can only toggle night light from the settings.

    Edit: It's not Arch, it doesn't work on Tumbleweed either

    Just tried your Kwin-lowlatency for 5.18, and WOW! It really did make a difference! I don't know what it is, but it's running better than Kwin-lowlatency on 5.17.
