[Regression] Video appears in lower-left corner only

[Shoegzer]

Video now appears in lower-left corner of the screen only, whereas before it properly filled the screen.

Bad commit observed: dd90d0e
Last known good commit: 49ca8c1

Options used:
-force-feedback -res=1024,768 -vsync -fullscreen -quad-rendering

• OS: Linux Mint 22 / kernel 6.8
• GPU: NVidia GTX 3070 / driver 535.183

That's weird, because we haven't made any changes since 49ca8c1 that should affect video output. I tried running Supermodel with the same options, albeit running Windows 10 instead of Linux, and I was unable to recreate the problem.

I assume that you're compiling Supermodel yourself, are you sure that you are compiling both commits with the same options?

[Shoegzer]

@gm-matthew yeah I thought it wa strange too. I'm building the project myself with gcc-14.0.1.

Build options are the same before and after these commits: make -j9 -f Makefiles/Makefile.UNIX NET_BOARD=1

[Shoegzer]

Another point to add, I'm using the following runtime options:

-force-feedback -res=1024,768 -vsync -fullscreen -quad-rendering

I've tried removing -res and -vsync but I still get the issue. I'm not sure if anything else would help.

I need to also mention: this occurs on a notebook hooked up to an external monitor. If I launch supermodel on the notebook screen, the video appears as it should. So I'm guessing it's due to some kind of frequency issue with the monitor? That said, again this wasn't occurring until the commit noted above, but as you said I'm not sure why it would matter.

I'm fine with closing this issue if you think it's beyond the scope of this project, but I'm at least curious on any thoughts you or others may have.

the issue is probably to do with multiple monitors, supermodel doesn't really have built in support for multi screen setups

[Shoegzer]

That's fair. I do have another monitor setup which is an arcade CRT though, it would be ideal for the project to support these kinds of setups as part of its presumed goal, though I'm sure there are other priorities.

That said, I don't want to beleaguer the point - I'm fine closing this if you think it's for the best. If you ever need help testing code that aims to tackle this in the future though, I'm happy to help.
