Weird extra scanline in VS builds

[tmaul]

As noticed by @dinkc64

There seems to be something odd about the game area (placeholder screen / emulation area) being pushed down 1 line of pixels. This happens in both the X64 and 32 VS builds, not the gcc builds. It happens regardless of blitter. Here's a pic of what I mean:

VS 32/64bit screencap

GCC build:

I thought this might be a .rc file thing where maybe VS2019 is compiling it differently than GCC but I have no idea if that's even a thing.

bad math ? feels like some kind of rounding issue to me

[tmaul]

Some more notes: This is only happening with certain blitters. E.g. doesn't happen with softfx. As @dinkc64 predicted it is happening in int ScrnSize()

[tmaul]

Also, at least for me, this is happening in GCC builds with the experimental and dx9 alt blitters.

[dinkc64]

That's weird! I can't make this happen here :/ Even with the latest win32-gcc.7z from the download link.

maybe it's been solved since the past two months

@dinkc64 That's very interesting. Is there any chance you can send me a copy of your own build via the forum or something?

I now think its one of a few things:

1. graphics drivers
2. a bug in VS and appveyor GCC builds (but then that would mean that everyone would see it)
3. still a bug somewhere in the insides of burner

[dinkc64]

Sure :) sent!

[tmaul]

This still happens with the build from @dinkc64

I'm still looking at it when I have time :)

[dinkc64]

That's really strange, I remember when it was happening and I could see it - but now it won't reproduce on my pc with any of the builds. gremlins!

[mobasuite]

It's your monitor.

Bug finally fixed, big thanks to tmaul, he gets at least half the credit here, without his support, I wouldn't have been able to run VS on my pc to do anything :)
