CE OSD Glyph from GVAR Overflow

[daedalusfpv]

Current Behavior

When using a Custom OSD element to display an OSD glyph, using an integer value assigned to a GVAR, GVAR values higher than 255 experience overflow behavior. OSD Glyphs with integer IDs greater than 255 are not available for display.

Steps to Reproduce

1. Assign value of 300 to a GVAR
2. Set up a CE using GVAR to display OSD Glyph
3. Observe the displayed glyph is not expected SYM_AH_LEFT, but is instead a comma character (255 offset)
