The artifacts in question:
These artifacts are positioned consistently across multiple executions of the application. I took a screenshot of the program immediately after startup multiple times, and the images are all the same as above.
If I resize the application window, the artifacts change aspect ratio to match:
If I run the turn_based
example project and load a fireball or if I load the transparency
project, then the artifacts blink briefly before going away. The artifacts do not return if I load other projects, but they do return if I shut down game_loader
and start it back up.
Removing this line from api.cpp
eliminates the artifacts:
if (Graphics->Settings.UseLightingBloom) { GaussianBlurTexture(&Graphics->Gaussian, &Graphics->Lighting.BloomTex, &Graphics->Lighting.BloomTextureFBO); }
I tinkered with this line in Lighting.fragmentshader
, removing one term at a time and testing, and each time the artifacts remained:
TotalLight = (Diffuse*KeyLightContrib*ShadowVisibility) +
(Diffuse*AmbientLightContrib*BlurredAO) +
(Diffuse*BackLightContrib*BlurredAO) +
(PointLightsContrib*BlurredAO) +

Those are the latest drivers for my OS, but the previous version (535.161.07-0ubuntu0.22.04.1) are the recommended drivers.
