Flickering with Intel HD Graphics 620 #246

Closed cjritola closed 3 years ago

cjritola commented 6 years ago

Random flickering when a portal activates, strips of terrain flicker to portal view (sounds like texture ID corruption), local models are randomly switching to models found in the tunnel.

Going to wait until Mesa 18.1 is mainstream on ubuntu and will investigate further if problem persists.

There seems to be some issue with render-to-texture. May have seen this issue with intel 4600 a few years back among other issues. The other issues had to do with unbinding the framebuffer a certain way specific to intel gpu which the other gpus didn't require but I don't recall exactly what it was.

The flickering is highly random; even pausing the game causes the flickering to occur. There seem to be scenes from other cameras melding together with the existing scene.
