Text seems to be "cut off" - Depends on TypeFace instance?

[0x3C50]

Hi, I'm completely at a loss.

I have a bit of a weird setup, that being integrating skia into the Minecraft renderer. Everything seems to work, but text refuses to work properly. Depending on the TypeFace instance, the text being drawn is either clipped (with no clip being present!), fully visible or not visible at all. An example:

As mentioned, the clipping is dependent on which TypeFace instance I use. Reloading the screen changes how much is clipped, if anything. Note that the actual font isn't being changed, the instance is just remade.

This happens with local fonts, as well as system fonts. All TTF. Even checked with the JB Mono font from the examples directory, that also has the problem.

My code so far:

// Init:
Typeface tf = Typeface.makeFromFile("/absolute/path/to/JetBrainsMono-Regular.ttf");

// At render:
Paint whitePaint = new Paint().setColor(0xFFFFFFFF);

try (Font font = new Font(tf, 32, 1, 0)) {
	font.setEdging(FontEdging.ANTI_ALIAS);
	canvas.clear(0xFFFF0000); // Fills the entire screen; Clip is not present
	canvas.drawString("hello??", 100, 200, font, whitePaint); // Cut off?
}

Caching the Font has the same effect.

Weirdly enough, the examples work for me, and text there renders properly.

This is probably an issue with my code, but I've tried for the past 2 hours to get it working, and my only real hope is that someone here has experienced a similar issue and can share their experience.

Thanks

Yeah. Weird that each letter is cut in half. Feels like there’s a factor of 2 missing somewhere. Where do you render to? Is there scaling set on canvas?

The canvas is scaled, yes. Without scaling, the same thing happens. The save stack should be empty when arriving at the drawString call. The canvas is managed by the GPU. I can send the setup code for that in a few hours if that might affect anything.

For some ungodly reason it works perfectly fine in another spot in the rendering pipeline - some state modified by the game seems to break it. Even calling resetGlAll before drawing doesnt fix it. ?????

Some more testing: when the glyphs are generated BEFORE any real rendering is done, it seems to work. only if the game has initialized properly and has a world loaded, do the glyphs not bake properly. Something something opengl state / textures?

Try DirectContext::reset (All/GLAll/Gl)?

sadly doesnt seem to affect the problem. I'm already calling resetGlAll before drawing, calling resetAll instead has the same effect. I think skia just doesn't work well with an existing opengl context...
