Since this is a "blinking" bug, do you notice any difference when you change your vsync setting? I would be interested to know if it looks any different as you cycle vsync between off, on, and adaptive.
The disappearing triangle is fixed but this bug is still present.
As of 6490, we may have a fix for the disappearing triangle problem, thanks to Fox. Please test, and also look out for any side effects that may have been introduced.
The error was due to bad coordinates being used for the vertices of sloped sectors. Back then the flickering happened all the time, but I suppose some optimization of getzsofslope limited the glitch to sloped sectors.
Didn't exactly know where to put this, so I posted it under "graphic problems".
Using the latest build : 20171229-6576. Using the polymer renderer. Nvidia Geforce 1060-6gb ram.
Playing the level "LUNAR REACTOR". At first I didn't encounter any problems. Saved the game and upon restarting, I got the graphical issues as seen in the screenshot:
It's caused by invalid geometry, to my understanding due to part of a sector crossing into another sector. When it happens it uses the last valid state but this is not retained when reloading a saved game.
Another "issue" I've encountered using the latest build (7299)... Texture mode : "filtered" doesn't work anymore. All textures remain classic pixelated.
