KWinFT: KDE's KWin Forked To Focus On Better Wayland Support, Modern Technologies

[kon14]

It's maybe a stupid question, but why is he not supporting Mir? It uses modern C++, is Qt-free and desktop-agnostic.

For starters, nobody but Mate uses Mir and then almost nobody uses Mate.
There doesn't seem to be much in terms of community support for the project either.
It seems like Canonical's typical NIH syndrome backlash had a high toll on Mir, even though they were originally there with Wayland.

There's wlroots though, backed by Sway (and other lesser compositors), one of the two major players in Wayland compositor development.

ssokolow that’s very different from Qt CLA. KDE is right to ask for optional copyright. It protects Copyleft.

I agree. I was responding to "No CLA on this fork. That comes naturally because the original code is 100% Copyleft with no CLA.".

The original was KDE code so, depending on whether you consider the FLA to be a CLA:

A) If you don't consider the FLA to be a CLA, then the original didn't have a CLA either, so it's nonsensical to bring that up.

B) If you do consider the FLA to be a CLA, then your current statement that it protects Copyleft suggests that your original statement is confused because "no CLA" would be a bad thing in this case.

this not answer my question

As others have pointed out, "no." Translated, KWin & forks are highly unlikely to have decent Nvidia driver support on Wayland anytime soon. KWin & fork needs work on vanilla Wayland with GBM. Also, there is no guarantee that EGLstreams will ever work well unless Nvidia actively participates and/or changes its attitude with the open source community (see Gnome's status).

Nvidia is 60% of gpu marketshare.
I anticipate the question - who cares? Roman's employer cares.

Intel is market leader in GPUs. Of course, Nvidia has leading gaming performance and is well established in computing (cuda).

Great. Another 144Hz clone who likes to post unrelated GNOME stuff in a KDE thread. Shoo, shoo.

Civilized people tend to query when the correlation of an answer and question is illusive to them. You seem to refrain to a mediocre attempt to bullying. Bad luck.

Not invented here syndrome.

Not invented here syndrome.

Actually it's not Invented Here Syndrom. Mir uses modern C++ and is desktop agnostic. There is no other Wayland compositor out there which has these properties. Actually Roman Gilg replied to my question and he might consider this option:

Does this sync the compositor to the vsync signal like kwin-lowlatency does? (And actually like the other platforms do as well, Windows and macOS.) Whenever someone tries to use a timer to sync like kwin does, you always get stutters. kwin-lowlatency is perfectly smooth, just like the Windows and macOS compositors.

What can I say? You posted an answer that didn't answer the question that was asked, and it was a GNOME-related answer. No wonder I thought you were a 144Hz clone.

The question was will "will Kwin support Nvidia driver." The answer is no, don't hold your breath, this is difficult - see Gnome. Sorry you did not get it the first time.

I'm neither Gnome or KDE, I mostly want the DE to go out of my way. That being said, people get on my nerves that are stuck in a KDE vs. Gnome mindset. This is not the 90s. They are both great for what they do. However, if you want to know about Wayland/EGLstreams, Gnome is your only reference that tried seriously.
