i´m porting some VL system from Beta 37 to Alpha 38.2 Build: 22 04 2019 14:26:58
The system consist in 3 devices connected, sending and receiving Midi, and a Skia UI.
The beta 37 version works fine, and reconnect midi devices is fast and not invasive.
In the Alpha seems reconnect midi devices does not work as in Beta 37, it takes much longer and sometimes it does not recognise new devices or disconnect some of the already connected.
Also FPS goes down a couple of times until the background operations finish (i don´t know exactly what).
Did you change something on this side since Beta 37?
Edit: It does not work with more than 2 devices.
