drawing an eclipse instead of a circle

Hello!
Issue: drawing an eclipse instead of a circle.
Same problem with other geometric shapes.
The square is stretched along the y-axis.
Functions u8g2_Setup_uc1638_240x64_f, u8x8_d_uc1638_240x64 and struct u8x8_uc1638_240x64_display_info were added to the library.
The struct members look like 8x8_uc1638_240x128_display_info but the last six are different.

  /* tile_width = */ 30,		/* width of 30*8=240 pixel */
  /* tile_height = */ 8,
  /* default_x_offset = */ 0,	/* lower nibble: x offset, upper nibble: y offset */
  /* flipmode_x_offset = */0,	/* lower nibble: x offset, upper nibble: y offset */
  /* pixel_width = */ 240,
  /* pixel_height = */ 64

Please, give reason behind this and advise me.

The display info struct is used to describe the display dimensions. Obviously a 240x64 display differs from a 240x128 display in the size of the pixels.
