Glitch or bad design during booting on Mojave? After enabling FileVault with recent T2 firmware patch the loading bar looks weird like its missing pre-cached image:



I replaced default Mojave.heic with a test image and gray "transparent" area kept test image framed while the rest of the screen remains black after system switched to user scale. Setting Display -&gt; Scaled back to Default  returning smooth booting. Is this a design issue or missing cache?

The firmware controls that rendering process and it’s by design not using the full graphics library so it’s hard to say if it’s a glitch or hardware issue or if an engineer figured the risk (or manager figured the priority/cost) to embedding more code outweighed the “let’s be pretty about everything” design goal.

Time will tell if Apple patches that or if others can reproduce it on their equivalent hardware and then you’ll know if it’s hardware defect, by design and if that design got someone to tweak the code / drivers to remediate that visual artifact.
