OpenGL driver crash on glTexture2D


with the following Kotlin/JVM/LWJGL + java.nio.ByteBuffer + OpenGL code it seems I can crash some driver of mine:

val texture = glGenTextures()
glBindTexture(GL_TEXTURE_2D, texture)

val w = 1026
val h = 1029

val byteBuffer = ByteBuffer

glTexImage2D(GL_TEXTURE_2D, 0, GL_R8, w, h, 0, GL_RED, GL_UNSIGNED_BYTE, byteBuffer)

Executing this after the usual GLFW+OpenGL init, this results in a crash of the application and the following message:

# A fatal error has been detected by the Java Runtime Environment:

Is there something I can do about this, but to avoid non-power-of-2-textures?

I tested some resolutions, and only got crashes with textures with width or height > 1024. In the case of 1026 x 1029 (and some more, e.g. 1590 x 2244) I get a crash in 100% of the cases.

I am using an RX 580, R5 2600, Win 10, Radeon Drivers updated to Recommended, just in case it would change something.

The default alignment for rows in the image data is 4 bytes. Unless your texture has a width which is a multiple of 4, you have to supply additional bytes for padding at the end of each row.

The other option is to change the unpack alignment to 1 byte by calling

glPixelStorei(GL_UNPACK_ALIGNMENT, 1);

before calling glTexImage2D.
