[🐛] Anisotropic filtering causes texture artifacts in true color #392

Closed JakeSmarter closed 1 day ago

Version: v1.09.540-264-g341db341+ OS: Linux Distribution: Flathub

When “Anisotropic Filter Quality” is set to 1.0 in “True Color” mode you can see artifacts on texture edges where textures repeat. This happens when using the hardware GPU as well as Mesa 3D’s software renderer. This leads me to suspect that there is a bug in the anisotropic filter algorithm.

The algorithm is fine, the issue is that the setting is too high for the padding size and needs to be adjusted. This should be fixed in the next release.

I am happy you were able to track down the issue.
