| Summary | 0029337: Visualization, TKOpenGl - visual artifacts on Intel Broadwell GPU | ||||
| Description | The random visual artifacts occurs on the screen when using Intel Broadwell ('2013) GPUs (Intel HD Graphics 5500, Intel Iris Graphics 6100).
GLvendor: Intel
GLdevice: Intel(R) HD Graphics 5500
GLversion: 4.4.0 - Build 20.19.15.4531 [GLSL: 4.40 - Build 20.19.15.4531]
This issue, however, does not affect other tested Intel GPUs (older and newer) as well as GPUs of other vendors, which looks like a bug in OpenGL drivers. Nevertheless, it is desired to have a fix/workaround for this issue on this platform. The issue appeared after integration of new Weighted OIT algorithm in OCCT, which implies multiple Render Targets, though the problem occurs when OIT is actually disabled. | ||||
