TechPowerUp reports a lot of MacBook Pro (model 2017) users are suffering from a display backlight flaw that causes a dark gray band to appear on the bottom edge of the screen. The issue is somewhat similar to the "Stage Light" flaw that was observed in the 2016 model. It affects aging MacBook Pro (2017) laptops but disappears again as you power down the laptop or close the lid for a while:
The 2017 MacBook Pro model appears to routinely start failing on the bottom edge of the screen with a soft gray bar appearing. This flaw appears thin on a cold-booted device, and spreads over time with use, as the device heats up. It dissipates as you power the MacBook down or close the lid for a while. The band distorts all content in the region of the display that it affects, including the macOS Dock, and vertically-scrolling content such as web-pages or text documents, and can be particularly bad for content creators working on tasks that are sensitive to display quality, such as Photoshop. Apparently, a small PCB located near the base of the display panel, which handles connectivity of the display with the mainboard, heats up over time, causing the LED backlit film to distort or the display controller PCB to malfunction.
There are hundreds of complaints about this issue on various online messaging boards. The problem was first reported in May 2020 and unlike the issue with the 2016 model, Apple is keeping its eyes shut. The only solution at this point seems to be a $600 replacement of the screen but that may only be a permanent fix as the problem will likely re-emerge as it's a problem with the hardware design.
