Description

Game Name?

Digimon World 4

Game ID?

GDJEB2
GDJJB2 (Japanese)

MD5 Hash?

65c7b4887d21efd526a69ff060f631b5

What's the problem? Describe what went wrong.

Text shows a couple of lines that are not normally present, and the position of said lines changes depending on the resolution. When enabling Wireframe mode, you can actually see that the wire lines match with the ones shown in rendering like normal. Pitctures below, I've added yellow arrows to point you better (zoom in, it's pretty difficult to see):



What steps will reproduce the problem?

Boot the game, Press Start -> Start Menu.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

I've started using Dolphin when it was still in 4.xx, and even then the bug was already there. I've tested with the original 5.0 as well as 5.0-7179, it's still having that problem.

Happens in both the J and US roms, but I find it easier to spot using the US one.

What are your PC specifications? (CPU, GPU, Operating System, more)

i5 4590
16gb DDR3
Z97m-D3h
AMD Radeon RX460 (bug also happens on the intel iGPU, as well as a Nvidia card when I had it).
120gb SSD

Yeah that happens in a lot of games in various ways. It's related to a few issues already on the tracker. Best thing you can do is hand us a fifolog.

Should I record it from before loading the menu or after it's already loaded?

So... help?

#5 Updated by JMC4789 9 months ago

You'd record the fifolog while the menu is up. Odds are that 1x IR will fix this. A lot of games have rounding issues like this, unfortunately.

#6 Updated by Imakuni 9 months ago

Done with the latested 5.0-7698 build. I hope this helps, tell me if you need anything else.

#7 Updated by JMC4789 9 months ago

The text doesn't appear to be on screen so I can't do much with it. Sorry if I wasn't clear.

Record the fifolog when the issue is present.

#8 Updated by Imakuni 9 months ago

I swear I did it, but guess I'll try again. Also, here's a video of me doing the recording, in case it fails again.

Yep, this one works. If you set it to 2x Internal Resolution + Vertex Rounding Hack, the lines disappear for now.

Broken at 1x IR is a big deal though.

#10 Updated by Imakuni 9 months ago

In this particular menu, yes, 2R + Hack works. But just going to another menu with other text, you can see it with the lines again, even at 2 IR and Vertex hack

#11 Updated by JMC4789 9 months ago

That could be bugs in the actual game though. We'd need to compare it. There are text issues in other games.
