Hello, I have a problem when create the GUI in full screen. The fact that minecraft scales resolution in gui and etc. I have a question, is it possible to disable it, that the resolution is not scaled? My code:

glMatrixMode(GL_PROJECTION)
        glMatrix {
            glLoadIdentity()
            glViewport(0, 0, mc.displayWidth, mc.displayHeight)
            glOrtho(0.0, 800.0, 600.0, 0.0, 1000.0, 3000.0)

            glMatrixMode(GL_MODELVIEW)
            glMatrix {
                glLoadIdentity()
                glTranslated(0.0, 0.0, -2000.0)
                glClearColor(1.0f, 1.0f, 1.0f, 0.0f)
                glClearDepth(1.0)
                glClear(GL11.GL_COLOR_BUFFER_BIT or GL11.GL_DEPTH_BUFFER_BIT)
                // render something
                glMatrixMode(GL_MODELVIEW)
            }
            glMatrixMode(GL_PROJECTION)
        }

P.s. glMatrix ->

GLStateManager.pushMatrix()

block() <- Kotlin blocks

GLStateManager.popMatrix()

Well first and foremost stop using GL11 directly. Use GlStateManager.

Why do you need to disable the GUI scaling exactly? You can easily draw anything you want based on width/height and have your fullscreen GUI independent of the scaling factor.

You don't actually need to be pushing/popping matrix here at all because if you are doing it in the middle of your operations you are screwing them up and once your drawing is done the game will reset the matrix anyway.

The matrix mode is already modelview though. You've just set it to modelview 7 lines above and you haven't changed it.

glClearColor(1.0f, 1.0f, 1.0f, 0.0f)

glClearDepth(1.0)

glClear(GL11.GL_COLOR_BUFFER_BIT or GL11.GL_DEPTH_BUFFER_BIT)

Any reason you are doing this? The game just did that for you like 6 operations or so ago. You are not using a different framebuffer after all and the one currently in use has just been cleared.

glViewport(0, 0, mc.displayWidth, mc.displayHeight)

You don't need to be doing this. The viewport is already set to the game's display width/height. Or to the custom framebuffer's resolution. In fact you could be screwing up someone's framebuffer setup by doing that.

 

Apart from all that looks fine-ish to me. Fix all that and see if you have any more issues.
