I am using LabelNode to display text when an entity is moused over and LabelControl to display text for HUD elements. I have 5 machines where the text looks correct but on one machine some letters are grayed out. The font color will change from white to dark grey in the middle of a word. I also see this behavior in the OSG statistics screen. Has this been encountered before?
I am running with OSGEarth 2.7 and OSG 3.4.0 on a Windows 10 box. My video card is a NVIDIA GeForce GTX 1060.
It looks like it was a driver issue on that machine. Apparently the machine has both an Intel Graphics Driver and a NVIDIA graphics driver. Disabling the Intel graphics driver made the problem go away.
