While playing the "night" showcase my game suddenly started to glitch about halfway through the mission. It started with a few objects stretching across the screen temporarily and ground textures becoming invisible before progressing to every object being stretched. I quit the showcase and was able to navigate the menu's perfectly although I noticed that the live image background showed some distortion. I then loaded up the editor and placed a single blufor rifleman and entered the game only to find that the issues was the same and that all objects were stretched rendering the game unplayable. The menu UI still functioned as did the HUD UI. Upon restarting ARMA 3 the issue was resolved and laying through the showcase didn't cause the issue to reappear. {F20687}
