Follow-up Comment #1, bug #56571 (project octave):

What I get on Windows 7 with a recently built dev Octave 6.0.0)) is:

>> img_data = uint8(randn(6000, 8400)*255);
>> figure(); imshow(img_data)
>> warning: opengl_texture::create: the opengl library in use doesn't support
images with either dimension larger than 8192. Not rendering.

So it doesn't look like a bug but the error message could be more clearly
displayed in your case.
I have no time now to check whether this size limit is documented somewhere,
if not it would be a doco error. I'll leave it to other devs here to adapt the
title & maybe status in that case.

(FTR, I make my crossbuilds using the --no-system-opengl configure option. Or
what is is exactly called as I'm on Windows now so can't check)
