I recently had a problem using an SSD1306 on a PIC16F18313. The display would not show text until I reset the MCU by pulling the MCLR line low.
Looks like it's a charge pump delay problem. Something to do with the SSD1306_SETPRECHARGE handling. The only solution I've found so far is to call InitGLCD_SSD1306 explicitly at the start of my code - i.e. essentially calling it twice. I suspect you are not allowing enough of a precharge delay.
Incidentally, I note that it seems to be impossible to use PSet or any of the shape-drawing commands on a 16F18313, due to the nonexistence of the SSD1306_BufferAlias variable. The MCU doesn't possess sufficient SRAM for this array. Is there any workaround for this?

These issues are resolved since latest release.
