After an upgrade to the Pi and an update to the software, I have a nearly fully functional Zynthian.
However, there is still one issue that was consistent right from the start that I was expecting to be fixed in this process. At random, when an option from any menu in the Zynthian UI is selected using the select encoder, the loading animation begins in the top right corner and all four encoders stop working.
The touchscreen still works to switch between options, but I cannot select any of them to open. I am also unable to navigate back with touch gestures. The only thing I am able to do is use SSH or the Web UI to reboot the device, or if there is no internet access, pull out the power cable.
The top command shows that zynthian-gui is still using resources during this hang:
This happens at complete random, in no specific menu, after no specific time. This build was from scratch, but with all the same hardware a standard Zynthian contains, making a hardware issue seem unlikely.
This is the last step for a fully functioning build for me, so any help would be much appreciated
EDIT: After continuing to play around, I have found that if a layer is already loaded, all midi and audio input and output continues to work. Nothing but the local UI stops working.
