Graphic artifacts in Star Fox: Assault
Star Fox: Assault
Game ID? (right click the game in the game list, properties, info tab)
MD5 Hash? (right click the game in the game list, properties, info tab, MD5 Hash: Compute)
What's the problem? Describe what went wrong.
Graphic artifacts in Star Fox: Assault can be seen on the attached FIFO log. There should not be thin lines next to the green loading screen text.
What steps will reproduce the problem?
Run Star Fox: Assault and view the loading screens before the start screen.

Alright, perhaps this issue should remain open in case a future modification fixes the problem?
I also tested with:
1XIR + 2XMSAA - did not reproduce
1XIR + 2XSSAA - reproduced
2XIR + NO AA - reproduced
2xIR + 2XMSAA - reproduced
2XIR + 2XSSAA - reproduced
Can the title be updated to:
Graphic artifacts in Star Fox: Assault with non-native IR or SSAA

I may be wrong, but I believe this is related to Issue #10401 which plagues a number of games (that I mention in that defect). This is an issue that even occurs at 1x (if you look really closely at 1x no AA / other filtering you can see green lines next to the text) and I believe it is due to some bug with our texture coordinates.

The problem starts with native resolution here. The problem exists before this commit if a higher internal resolution is used though. There are a few issues where the same commits affect the various issues. Maybe this would be a case to open a new issue and have the various instances of this bug all duplicates of it?
Issue starts in 4.0-1474 for 1 x IR -> https://dolphin-emu.org/download/dev/25f5598e31d5ce5dca8d1b03888a9205b616280e/

I think iwubcode is right. I recorded a different FIFO log that has obvious artifacts near the words "High Score" with 1X IR, no AA, no AF. Can we update the title again?
I suspect that the artifacts in that file select screen (e.g. "High Score" in the screenshot SFA 2.PNG) are due to Dolphin using different fonts from those in the actual GameCube BIOS (See --> https://wiki.dolphin-emu.org/index.php?title=Star_Fox:_Assault#Improper_GameCube_Font).
I've attached a screenshot from a YouTube longplay (https://www.youtube.com/watch?v=uuH-zUZVMec) that was recorded off original hardware, showing the font differences. The IPL font is a bit thicker and more spaced out than the Dolphin one. Issue #8362 suggests that the width differences between the two fonts can cause graphical issues, which could explain why 1xIR still causes problems in that menu.
The loading screen fonts in both Dolphin and hardware capture are seemingly indistinguishable. That one definitely seems like a texture coordinate issue. It is consistently reproducible on my end with 5.0-13963 when anti-aliasing is enabled and/or a non-native IR is used. If someone can verify using a dumped GameCube BIOS that 1 x IR doesn't leave text artifacts on that file select screen then perhaps the Subject text should be reverted to clarify.
