A few weeks ago my Pironman 5 OLED screen began displaying degraded text. All the text looks low-res and is harder to read than it used to be; the CPU and temp text has characters that appear to be in a bolder text than the rest of the characters. When I first started with this case, the text was all uniform.
We recommend providing images or a video of the issue, as it is possible that prolonged operation has caused damage.
