Why cant it naturally grow and prove it's worth?

Consistency of titlebars has been dead in every OS for decades now. This is not even a flatpak problem anyway, but I do think wayland/gnome ought to have some kind of fallback decoration. This wouldn't even be meant to solve this problem, but would be a nice gesture for situations where a dev really don't care about how the decoration functions or looks, like when opening a game window or movie player like mpv or even just having a friction-less experience when creating your first window in a new app.

> tray icon w/light and dark mode support

Flatpak and specially gnome are championing the background app portals. I have reservations on how it's not a full replacement for tray icons, but Desktop Environments are free to implement it like a tray icon.

> global keyboard shortcut

AFAIK it's a solved problem, but there is an adoption lag for DE's and apps.

> redraw events after resizing

Not sure what you mean by that? Apps resize fine in flatpak

Every problem in flatpak can be addressed. It sucks they weren't addressed sooner but I suggest you look into the efforts being made for flatpak-next. Even right now it's the closest thing we got to a unified gui experience in linux.

All these issues can happen in any platform, Linux is just the more annoying/unpredictable one, with GNOME taking the cake for being so obtuse. There is either a carelessness from the developer or the ad-hoc nature of those "tray icon" systems is to blame.

The point is, even if you could get a smooth experience it was at best an exception, specially across most of X11 life. There are many reasons why the Steam Deck shipped with Steam running through the gamescope micro compositor, and one of them was sidestepping some of the X11 jank.

That same year I decided to give Wayland my third shot and what you know... it not only was perfectly smooth all the time but it had finally reached a point where I could use it on my HTPC. Less than a year later and it was finally usable on my desktop and laptop, and since then I haven't really looked back.

It is already possible, modern n64 techniques and microcode are scarily good:

When doing 4k@120fps 4:4:4 chroma you might have to deal with longer handshakes and sometimes even no handshake at all. Or random dropouts. Or HDR not activating properly.

That said, Linux used to be a tough cookie because there were so little support for software people wanted to run and the alternatives didn't do it any favours, plus the barrage of problems you used to get installing it on a random machine was discouraging, at best. Nowadays your chances of running it well on a random machine is pretty damn good and getting the software you need is lot more feasible. But don't go YOLOing a linux install, see if meets your use cases. There is nothing wrong with waiting until it's good enough.

I never knew there was a TTF variant, might be a good fit on software that stubbornly blurs it when rendering in hi-dpi.
