On some hardware/systems, blender may crash when adding, rendering or displaying Grease Pencil objects. In `/source/blender/draw/engines/gpencil/shaders/gpencil_vert.glsl`, line 35: ``` gpMaterialFlag gp_flag = floatBitsToInt(gp_mat._flag); ``` `gpMaterialFlag` is of type `uint`. This is a mismatched-type assignment that can cause crashes on some hardware/systems with GLSL that do not support implicit type casting. So use `floatBitsToUint` for type conversion.
