I am. It's been on my radar for a long time and I have prototypes for one that are bitrotting on gitlab. There are three major design pieces of it. First, It has an executable that runs in your development container (environment/e

Surprisingly, still GTK 3 which means software rendering. If they get it to GTK 4 and recent WebKit release they'll get a lot of DMA-BUF usage to bring many of those WebKit->GTK->Compositor copies to 1 (or in some offloading case

It's extremely easy with GTK these days too because libpeas has a luajit backend (along with SpiderMonkey, Python, and of course anything native) and they all are backed by GObject Introspection to call into the C libraries/app.

You can't pipeline X11 operations in the presence of anything but a perfect network because 1. TCP streams require stalling when packets are dropped to keep the stream in order 2. X _requires_ by design that commands are performed in o

Describe "just"? How about input events? How about vsync synchronization? How about monitor information? How about clipboard? How about drag'n'drop? GDK does an awful lot of lifting for Just here.

Hi, I'm the author of almost all of those VTE performance improvements. I wrote them because the latency in gnome-terminal, which I've used for well over twenty years, was starting to make me miss-type due to how slow the feedback

> Flutter Desktop seems like a compelling alternative to GTK these days. Sad news for ya, flutter just wraps GDK (from GTK) on Linux. It also, last time I checked, was limited to a single application window.

Linux version doesn't have aarch64 builds in case you try Flatpak and it doesn't work.

The application runs inside of the Flatpak sandbox and therefore has a different mount namespace, PTY namespace, PID namespace, etc. That makes tracking foreground processes for simple things like "is the user running something when th

The big difference here from Console is that Prompt will do custom snapshotting for the TabOverview to make it fast. Otherwise it thrashes the glyph cache. Of course, I also wrote the glyph cache for GTK, but it's just not something I

It discovers the location of `prompt-agent` from inside the Flatpak and executes it similarly to how it would execute a shell on your host. The socketpair() is passed in to do FD passing. This of course only works because of careful selecti

There is an overlay now in gnome-terminal git that will give you this on wayland. I added it last month.

Presumably that would still cause issues at the rounded corners because you need to blend those pixels to make them look nice.

And even if it did, you can't do clip masks with scanout overlays. So you have to composite (and therefore take the hit of ramping up the 3d capabilities of the GPU).

When I wrote the macOS backend and GL renderer I made them use IOSurface already. So it's really a matter of setting up CALayer automatically the same way that we do it on Linux. I don't really have time for that though, I only wr

Drawables on Drawables doesn't help here at all. Sure it lets you do fast 2d acceleration but we don't use 2d accel infrastructure anywhere anymore. Subsurfaces have been in Wayland since the beginning of the protocol. This is sim

This would require protocol changes for X11 at best, and nobody is adding new protocols. Especially when nobody does Drawable of Drawables anymore and all use client-side drawing with Xshm. You need to dynamically change stacking of subsurf

Easily solved by black bars just like people are used to on a TV. I assume most video players will do this when in windowed mode.

No, you can already be sure it's the right size. This has to do with what it takes to occlude the rounded area from the final display.

by audidude 3y ago
If you have the video extend to where the corners are rounded, you must use a "rounded clip" on the video ontop of the shadow region (since they butt). That means you have to power up the 3d part of the GPU to do that (because the

I can't respond to everything incorrect in this, because it's way to long to read. But from the very start... Also, I wrote a significant part of GTK's current OpenGL renderer. > But GPUs change the picture entirely. From
