Emacs natively on Wayland (PGTK) is slower than on Xwayland (Lucid) Also fonts are not looking good on both (but good on X). (alien.top)

I have rebuilt Emacs 29 with PGTK in order to get Emacs running natively and to fix the fonts, and i already have another emacs 29 build (Lucid) installed with i use On X.
I was surprised to see Emacs on wayland was running slower than its counterpart on Xwayland. Also the fonts issue was not fixed.
While zooming in makes the fonts look better. On X i don't have this issue.
Below is screenshots of fonts on Wayland - Xwayland and X

Having had a hidpi monitor for ages, PGTK has been so great and so incredibly better at rendering fonts, menus, bars, etc, tan any X toolkit, and managing scaling correctly, that I switched while still was an alpha version in someone's github. The worst problem is that pixmaps are shown 1:1, pixel by pixel (being impossible to distinguish on a high dpi display), while the text is properly scaled, it's unusable.

Never looked back. Well, no, I've tried the X version a few times and it sucked, as I remembered.

As there seems to be quite a lot of hate for Wayland and PGTK I too can confess that all reasons of u/noi-gai are also my experiences for using Emacs on Linux. If there wouldn't be Wayland scaling support with PGTK I wont use Emacs GUI any longer, as everyting would be blurry.

Now I do not know what I miss by not using X as I do not wander back and forth but stick to Wayland since years. Oh I do miss proper GTK integration, but this is only ever going to happen with multithreading-support.
