> Does anyone think the move from GTK2 to GTK3 might be part of the issue or is that just a coincidence?
Likely just coincidence - this "white screen" problem has happened to 16.04 users too, and I've known it to happen to another WebKit2-based application too. The problem bizarrely just goes away with general system updates.
However, this is a tough one to fix, as it isn't a fault of Welcome but rather the WebKit2 library it depends on. Please check dmesg for errors or stack traces, which will help determine a bug report for the WebKitGTK developers.
