SpigotException

I had Minecraft in window mode at full size at 1080p. I also had it smaller, but nothing changed, so I don't think the resolution is the rendering problem. Maybe I'm wrong...

Hello, I'm pretty new at developing forge mods and wanted to use my own fonts for titles etc for the main menu. I created my own FontRenderer and overwrote the renderUnicodeChar method there, but the text still looks pretty strange. The custom class: import net.minecraft.client.gui.FontRenderer; import net.minecraft.client.renderer.GlStateManager; import net.minecraft.client.renderer.texture.TextureManager; import net.minecraft.client.settings.GameSettings; import net.minecraft.util.ResourceLocation; public class CustomFontRenderer extends FontRenderer { public CustomFontRenderer(GameSettings gameSettingsIn, ResourceLocation location, TextureManager textureManagerIn, boolean unicode) { super(gameSettingsIn, location, textureManagerIn, unicode); } @Override protected float renderUnicodeChar(char ch, boolean italic) { int i = this.glyphWidth[ch] & 255; if (i == 0) { return 0.0F; } else { this.bindTexture(locationFontTexture); int k = i >>> 4; int l = i & 15; float f = (float) k; float f1 = (float) (l + 1); float f2 = (float) (ch % 16 * 16) + f; float f3 = (float) ((ch & 255) / 16 * 16); float f4 = f1 - f - 0.02F; float f5 = italic ? 1.0F : 0.0F; GlStateManager.glBegin(5); GlStateManager.glTexCoord2f(f2 / 256.0F, f3 / 256.0F); GlStateManager.glVertex3f(this.posX + f5, this.posY, 0.0F); GlStateManager.glTexCoord2f(f2 / 256.0F, (f3 + 15.98F) / 256.0F); GlStateManager.glVertex3f(this.posX - f5, this.posY + 7.99F, 0.0F); GlStateManager.glTexCoord2f((f2 + f4) / 256.0F, f3 / 256.0F); GlStateManager.glVertex3f(this.posX + f4 / 2.0F + f5, this.posY, 0.0F); GlStateManager.glTexCoord2f((f2 + f4) / 256.0F, (f3 + 15.98F) / 256.0F); GlStateManager.glVertex3f(this.posX + f4 / 2.0F - f5, this.posY + 7.99F, 0.0F); GlStateManager.glEnd(); return (f1 - f) / 2.0F + 1.0F; } } } Preview of the custom font. I initialized the renderer as follows: FontRenderer fontrenderer = new CustomFontRenderer(mc.gameSettings, new ResourceLocation("mountainmod", "textures/font/cammron/ascii.png"), mc.renderEngine, true); My idea where the problem is is the size / resolution of the ascii.png. The ascii.png of Minecraft is 128x128 pixel large, the ascii.png of my font(s) is 1024x1024 pixels or 2048x2048 pixels large (I tried 2 fonts). Best regards.
