How can I consistently create QOpenGLWidget applications to show up?

Sailanarmo

I will uninstall my graphics driver and reinstall them. I will let you know what happens.

I've uninstalled the graphics drivers and I attempted to launch the same application without the drivers. The same behavior happened. I then reinstalled the graphics drivers and launched the program, and the same behavior happened.

I could try downgrading my driver version. But I do not know where to go to find a lesser version of my drivers. I also don't know, why Qt chooses to launch one application, and not the other just fine. It's all very confusing.

I just launched the program from my home. It launches just fine. Only difference is that I am running a GTX 1080ti instead of an RTX 2080. I know I am repeating the same thing, but I do not understand why the linux machine with the same physical graphics card runs the program fine. But when I switch to the windows partition, it craps out.

I'm kind of at a loss here. Maybe it is a hardware issue within windows itself. Or maybe it's a one time fluke and it is only affecting me.

As I already said, it's likely a driver issue. While sharing the same version number, the architecture is different between these two OSes.

@SGaist

I rolled back the drivers to when I first built this computer. I am running 419.17 now instead of 419.67 which is the current version. This is the driver I was using when my first application started. The same issue is happening.

I really do not think it is a driver issue if I am going to be completely honest. You do know more than I do, so maybe you are correct, however I feel if it were a driver issue I wouldn't get inconsistencies with different programs using OpenGL (meaning some programs that I created using Qt and OpenGL work and others do not). The other thing that suggests to me that it isn't my driver, is the fact that I can create a separate OpenGL application without Qt just fine. But it does me no good if I cannot use Qt to work on my projects.

Another more drastic measure that I have given thought, was wiping the OS entirely and starting from scratch. However this is the last thing that I want to do because this takes a lot of time and causes big headaches.

Thank you again for all of your help.

EDIT it appears I haven't rolled them back

EDIT 2 I am running 411.70, I'm assuming this is the earliest driver that NVIDIA Automatically provides with the graphics card. And it is the same behavior. Again, I do not think it is the drivers. But it seems we have beat this to the ground as far as we can go.

I put a break point in main and ran it with a debugger, I pressed paused when nothing happened and this is what came up. It doesn't mean anything to me, but maybe it means something to you.

UPDATE A REALLY Weird one, once I discover the solution I will mark this as solved.

@SGaist as I suspected, it was not the drivers, the drivers are just fine. However, it could be the configuration of my setup that is causing it to crash.

Essentially I am running two monitors, both using display port, and both are connected to my graphics card. When I try to launch the program on my left monitor (meaning the secondary monitor) the program halts and crashes. However, if I launch the program on my right monitor (the primary monitor) the program launches just fine. And this is with all openGL applications. So I will try and figure out the root of this cause and I will mark the post as solved once I figure out how to launch it on both monitors.
