| Summary | 0029508: Visualization, TKOpenGl - visual artifacts on Adreno 305/308 | ||||
| Description | The visual artifacts occur on the screen of Samsung smartphones having Adreno 305 and Adreno 308 [ASUS ZenFone 4 Max / ZC554KL] (both are limited by OpenGL ES 3.0). There were no such issues on OCCT 7.1.0. Note that artifacts are obvious only within Phong shading model; within per-vertex lighting image looks fine. The problem occurs when Phong program is compiled being marked as "#version 300 es" on these devices. | ||||
