High Quality Pen in Fullscreen

I've been working on an entirely pen-drawn windowing system and I noticed that pen trails look alright in normal mode, but in full screen mode, it looks very low quality


Normal mode

Full-screen mode

It could be antialiasing due to a larger screen size. (Oh, this is a feature request. In which case, I second this.)

I don't have that problem... Chrome, Windows 11...

Yes you do..? This isn't a problem, it's literally what happens when you attempt to resize pen trails generated in morphic.js. Also, both of these screenshots were taken on Windows 11 via Chrome

Ah, I see what was going on. I used the script in the post you linked to:


When I entered full screen, it redrew the window and was high quality. I experienced the same issue as you when running the above script and then stop [all V] .

However, testing once more, it has arbitrarily stopped being an issue for me:

Higher quality screenshot, full screen:

So I'm confused.

That's so weird

it doesnt do that for me. when I let the window redraw, even in full screen, the pen trails are low quality
firefox on linux

For me the pen trails are also low quality in full screen but also when I make the screen larger. I am using Chrome in Linux.

Here is an example. Full screen with linewidth at 40

@bh is this a bug or am I missing something? Is this only happening on linux?

Happens to me no matter the device

For me it happens always, not only with full screen. It wasn't like this. FireFox does it also.

i can confirm that it happens on linux, I have the same low quality pen regardless of the stage size
what distro are you using?

I use Fedora.
