One question doe, why does it take that much for the terminal to fill its own back color? I watched the video and saw that you were using VirtualBox (very fast when it comes to GUI rendering), it shouldn't be that long. Also how hard was it to port Cario Graphics? Is it worth it after all? Do you need to have a working compositor when using Cairo or it can be the compositor itself?
Thanks!
It's actually not the graphics stuff here that is causing the lag. In the demo I did a quick-and-dirty way to update the canvas size, that is set its bounds to the window size each time it is repainted, and that is slow
that will be done by the window server itself soon.

Yeah, you just need to update the canvas size whenever the window size changes. So when the window is initially created, if the window is resized programmatically, or if the user resizes the window. For the user resizing the window, it would probably be better to update it when the user completes the resize (releases the mouse button) rather than for each small mouse movement while they're resizing it, otherwise it might be laggy.

Completing a resize only after the mouse is released is sometimes called "lazy resizing" (you can also do lazy window movement in the same way, but it rarely has the same sort of advantages). I do this in my compositor by displaying a bounding box during the resize action and resizing the window only at the end.
Here's an old screenshot;
the bounding box aligns to window rotation.

here's something a bit less dated

"just"
When the canvas size changes and the buffer is not sufficient, the server resizes the buffer, posting an event to the client that there is a new buffer, the client repainting the content, sending an acknowledge-message to the server and the server then switching to the acknowledged buffer.
I thought about doing something like klange said, but I'll first try to see if it goes well like this, too.

Hello everyone! It's been a long while I didn't posted anything here.
It's been also a while I didn't worked on my own OS, but it's still alive and here is a screenshot of it.

I've seen your posts way back in this thread, and I've always been interested in your OS, but your website link has always been dead since I tried it in 2015. Is it still written in assembly? It's nice to see a project can still be alive after such a long time without activity, very inspiring.

You guys are making me envy!
Both of you: really cool operating systems, I wish that Basic OS was that good.

Yes, it's still written entirely in assembly. The project evolved a lot, but very slowly. I've added support for APIC (interrupt controller & timer), SATA (read/write), and SMP. However, it's still 32-bit and there's no UEFI support.
I've added a new screenshot of the OS with a different color scheme.

I got job control working, for those old enough to remember what that is. I'm using an unmodified cross-compiled bash shell.

That looks pretty nice @max
Gonna add round corners later too
Im about to implement labels to my gui, but before I have to finish my TTF drawing.
I try to use as little libraries as possible, I dont like bloated code in my kernel

Thanks Ch4ozz.

That's just an example from the cairo page; it's what I used for testing my client-drawn canvas implementation.
