Here's the time lapse video i recorded of the LoopA. I gave up on the solder paste and hot air method early in the build, as the solder paste I used didnt come with a plunger and my plunger was a bit too narrow. I have officially converted over to drag soldering now and its much faster. When I soldered the Mattias switches the recording stopped as a calendar notification popped up on the phone! Luckily its 99% of it is there! Thanks again to everyone involved, everyone is credited at the end of the video.

Hi ilmenator, I had the same issue but with a smt32, one LCD works fine, both -> garbage. It appears when suply voltage with the PC through USB cable, and fix it changing a 74HC595 with a 74HCT595 instead. so now it's working fine, but what you wrote ( and what Thorsten wrote ) is very important to me to understand the problem, may be a voltage level problem? in my case it seems i think due to the use of a 74HCT595, I'm not sure Thanks to Thorsten and you for this contribution Albert
