After extending the library for 64x32 screens (#53 b92bf18) a new batch of screens fail to work!
Following show(), just random data is shown on screen.
It is possible to adjust the contrast, so the displays seem operational, but there is something up with the framebuffer/RAM/correct addressing.

Possibly these other displays are SH1106 not SSD1306, which unlike the latter, only support page addressing mode.
See comments in this Arduino forum and also mentioned in issue #28.
