Hi!
I'm having a trouble using the "Browser" source. I have the "Linux browser" plugin which works, but not the native one. On Ubuntu 20.04. Searched around and only found about the file selector, which this isn't about.
Anyone know what it could be? It crashes in libcef, but I don't have debug symbols, so can't say where. Don't know how to build a dev version that'd have that yet.
It crashes when I click "OK" in the "Create/Select Source" dialog.
Could maybe my existing plugins be interfering, or something easy like that? It shouldn't really access wrong memory in any case though. So something is weird.
