Hi lacombe! I looked at the code and it seems pretty good, are you still working on it?

Hi there,

I have this error message "sRGB framebuffer is not supported by video hardware" on my notebook. I heard it is because LWJGL uses "GLX_ARB_framebuffer_sRGB" and "GL_ARB_framebuffer_sRGB", but not "GLX_EXT_framebuffer_sRGB". My notebook(Compaq Presario F763NR) has only "GLX_EXT_framebuffer_sRGB".

I hope someone can help.

Please see the attachments for the details from my notebook.

I notice that when you render the quads, you only setup a pointer for vertex attrib 0 which looks like position but you enable and expect vertex attrib 1 as well which looks like tex coords.

Code: [Select]
glBindBuffer(GL_ARRAY_BUFFER, vertexPointer);
glBufferSubData(GL_ARRAY_BUFFER, 0, RenderUtil.createBuffer(verts));
glVertexAttribPointer(0, 2, GL_FLOAT, false, 0, 0);
//MISSING CALL to glVertexAttribPointer(1, 2, GL_FLOAT, ?, ?);
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, RenderUtil.getIndicesPointer());
glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_INT, 0);

Now I don't know for sure what happens if you enable a vertex attribute but don't setup a pointer for it. Probably depends on whatever state you left it in but, it evaluating to a constant value (like 0) seems plausible. Which in this case would mean only sampling a single pixel of the bitmap texture. Which is what you recon is going on.

Might not be the case but probably worth a look.

UHD 3840x2160

I'm not familiar with how macOS handles external displays. What is the native resolution of the external display?

Just tested that, and that seems to be true of the internal MBP display. On the external display, the framebuffer size seems to match the screen size regardless of the hint.  Whether or not I use the macOS scaled mode at HD or UHD.  Which is good right?

Note that when creating a 1920x1080 window on macOS with GLFW, the window will cover the entire screen. However, the framebuffer backing that window will have the retina 3840x2160 resolution. You can get the framebuffer resolution using glfwGetFramebufferSize or the framebuffer size callback. To disable retina scaling, use glfwWindowHint(GLFW_COCOA_RETINA_FRAMEBUFFER, GLFW_FALSE) before creating the window.

So it turns out that there is some scaling in macOS, the 'Default' option is ignoring the monitor resolution. But by doing the magic hidden Alt-Click on 'Scaled' option a list of actual resolutions shows up, and from there it's clear macOS is defaulting to 1920x1080.  Although having tried the UHD mode, and as nice as the LWJGL looks, my eyes are just too old for text that small :)

oh and glfwGetVideoMode is obviously working perfectly fine.

btw using any other scaled option apart from 1920x1080 and 3840x2160 shows a warning 'using a scaled resolution may affect performance'.  I'll try these out when I have more than a cube to performance test against!

The info button on my monitor is showing 3840x2160, but glfwGetVideoMode is reporting 1920x1080.  Is there a scaling factor involved under the hood somewhere like on iOS? About this mac -> displays shows  (3840 x 2160) and I am using 'Default for Display' in the display preferences -> display -> resolution.  I'm a bit confused where the difference is coming from?

LWJGL sources are UTF-8 encoded. I don't see a problem locally, on github, or the generated javadoc.

What tool is producing these javadoc warnings? It's not a problem to change the curly quotes (they are there because the original documentation has them like that), I'm just curious to know why you're getting warnings for the source of a library your project is using.
