emacs-pgtk flashes white background on startup and displays blurry fonts

[Oleander]

Hello,
I recently learned that fonts in xwayland Emacs are a bit blurry due to 
fractional scaling being enabled. I installed emacs-pgtk (29.4) and fonts looks 
better compared to emacs/xwayland but they are still a bit blurry compared to 
emacs -nw (non pgtk) or vi/vim. Is it the same for you? Furthermore, when 
starting emacs-pgtk I experience this issue 
https://lists.gnu.org/r/bug-gnu-emacs/2022-01/msg00755.html and the suggested 
workaround does not work.

I'm running swaywm 1.9

Any hint?

Thank you!
