It may be because of the video card. If you have a dedicated video card, follow this step by step. https://www.youtube.com/watch?v=P1V6nQ-9vhY If you do not understand the language just repeat the steps of the video.
I am also seeng similar. Even with a basic cube.stl that works in any other slicer.
Graphics lines all over the place, and only the 'grey' shape of the object on the grid.
I've seen other posts mentioning Chitubox issues with integrated Intel GPU's ... my laptop is similar, it has an integrated Intel HD GPU, but its quite a powerful laptop. So I guess the graphics library you are using is using some API call that is not supported in these Intel GPU's.
My laptop specs are:
Dell XPS 9350,
Intel® Core™ i7-6500U CPU @ 2.50GHz
Intel® 100 Series Chipset Family
Intel® HD Graphics 520
QHD 4K Touchscreen (3200 x 1800 x 59Hz)
16 GB RAM
Microsoft Windows 10 Pro (64-bit)
I think you need to try support the Intel chipset as it is in many laptops, and desktops with integrated GPU. And its no good you only support NVidia top-end graphics cards etc, else you cut your customer base hugely. Also, the graphics in Chitubox is not that advanced thst it needs extreme GPU functions, you will find this is likely just one API call thats an issue.
On the requirements page it says, "OpenGL 4.0 capable system." Have you tried searching for, or ensuring you have drivers for OpenGL for the Intel integrated video on your laptop? Maybe that's the issue. It is somewhat possible that the manufacturer of the laptop didn't include that part of the driver stack in their install, or pre-installed if that is the case for your machine. So you might try installing the Intel driver stack for your video controller instead of the vendor specific driver.
I cannot guarantee this will make a difference but it might be worth a try.
