All of the early VLC 3.0 versions work fine until I get to 3.0.7. The changelog suggested that there was a sizing glitch fixed between 3.0.8 and 3.0.9, but that doesn't fix this issue for me. I haven't tested 4.0.
I'm digging around in the VLC source code to see if I can understand the problem, but can anyone point me in the right direction?
I'm using an updated version of the sample player given at: https://raw.githubusercontent.com/oaube ... s/qtvlc.py
