Does Graphicsmode works on all 0,96"-Displays?

[kinderschoko]

I have two different I2C-Displays with ssd1306. The left one is from joy-it and the other one is a super cheap one from ebay. I have connected them parallel and in textmode both of them are fine.
But when i turn the graphicsmode on, graphics and texts are shifted by one line up on the cheap one.
So when i use text for example in line 1, i cant see it on the cheap one and if i write it to the last possible line, there is a gap below.
Any Ideas?
