The subtitle issue is a known bug. Toggling full screen will reset the subs.

If you have an older and or underpowered laptop, using the browser might be a better experience. But only if your server is pretty capable and can transcode.

Jellyfin Media Player should direct play everything, whether your client is capable of smoothly playing the video or not. Depending on your laptop's specs, it may not even have the hardware decoders for most modern codecs and it is software decoding everything.
