All of the icons on the animation represent damage reports. The black triangles that stretch through Southern Texas and portions of Oklahoma represent hail that was greater than 2 inches in diameter. The minimum severe requirement for hail is 1 inch in diameter. There was also tornado and wind damage reported with blue and red icons. The image below comes from the National Weather Service in Norman, Oklahoma showing the large path of damaging hail with some locations seeing hail between 2-3 inches in diameter.

Down in Texas, just to the southwest of San Antonio, they had multiple tornado warnings, heavy rain, gusty winds, and large hail. On the lefthand side of the image below you can see pink, purple, and blue colors which indicate very large hail. There is even an icon with a 3 on it which indicates 3 inch size hail, that’s larger than a baseball! Hail that size will definitely cause damage to cars, home windows, and roofs.
