We've noticed that some games have an issue with the voodoo recompiler on the 64-bit version. Could you try again with the 32-bit version of 86Box?

I've tested the x86 version using 86Box-Linux-x86-b4869.AppImage and the issue persists.

Also in other test I disabled the Voodoo 2 recompiler in the settings but the issue is still there.

One other thing to try: Set the render threads to 2 instead of 4. Some games display artifacts when render threads are set to 4.

What is your host CPU? What drivers are you using in the vm? Some glide games are very picky about drivers.

Would you be able to upload this vm somewhere? The whole directory that contains config, nvr and disk image.

Here are the results using 2 render threads. Notice the same artifacts in the same game map location.

My host CPU is a Ryzen 9 5900X. I´m using the Creative 3D Blaster Voodoo 2 drivers from vogons, http://vogonsdrivers.com/getfile.php?fileid=132&menustate=0.

I've uploaded the vm in Drive https://drive.google.com/file/d/1q6C2PKw40C-PhhMYxCtoDalk8z5VLUAN/view?usp=sharing

Thanks in advance

That's the oldest Voodoo2 driver. I just tested it with the latest 3.02.02 driver from falconfly and the game works fine.

Even Voodoo1 was having that problem when using the built-in Win 98 SE driver (although not to that extent). Again, the latest driver fixed it.

Then this can be closed as NOTABUG, at least, not on our side.
