The problem

After update of ESPHome to 2023.12.0, the behavior of contrast setting on SSD1306 display changed. Changing contrast to value approx. 15% and less doesn't have any effect on the display, it's brightness doesn't decrease. Setting of higher values is visible. Looks like there is a minimal threshold of contrast which cannot be passed.

After downgrade to 2023.11.6 everything is ok again.
