Static noise when using crate with embedded_graphics about ssd1306

[blaa]

Try SH1106 library. SSD1306 ALMOST works ok with screens using sh1106, but doesn't clear them ok, and in the terminal mode the text is shifted a bit (and possibly many other small differences).

Your screen on photo looks exactly like mine - sh1106. https://docs.rs/sh1106/latest/sh1106/#

115200 is quite strange for I2C. Can you try 100_000 (standard I2C rate I think) or maybe 400_000?

You could also try adding a clear/flush just after init, e.g.

display.init().unwrap();
display.clear().unwrap();
display.flush().unwrap();

I've anecdotally had this fix the static issue for me in the past, but I'm still unsure of its root cause.

If possible, try a different SSD1306 module to check if it's a hardware fault. Some of mine just seem to die sometimes.

I've exactly the same problem:
Version of ssd1306 in use (if applicable): [0.7.1]
MCU/other hardware in use: RPPico
Display resolution and interface: [I2C], [128x64]

Replacing this crate by the SH1106 leads to the same result:

Ok, my bad. That was a power-on bad reset.
That was subtle because the device was partially functioning (DisplayOn/Off, Normal/Inverse, Contrast,...) but the commands related to the embedded display SRAM no. Then I presume the SRAM needs a well formed reset.
A lot of time lost for this :(
