Well.. there's a First Look forum and a Current Version forum...RC isn't either, so not sure if this is the right one, but it's where I'm posting.
Below is a list of problems I've found with the newest RC (1.20)
============================
Snapshot Doesn't always auto-preview:
I've got it so that when taking snapshots it gives a full screen preview. Sometimes when taking a snapshot with this newest RC however, it keeps everything in place, but the 'upload' button doesn't light up, and I have to click 'refresh snapshot' for it to register.
Not Consistent Settings:
Every time I log on, I have to turn three settings back on; Bump Mapping & Shiny, Flexiprim Quality (It's really low on boot up), and Nearby Local Lighting.
Crashing On Camera Movement:
This one only happens, as far as I can tell, after I've turned Bump Mapping and Shiny back on. Aside from that it's just the same as the old bug where if you move your camera, regardless of speed, it will sometimes crash SL.
Freezing Completely:
Occasionally SL with freeze my computer entirely, it's never done this before. I don't have my specs with me here but I've been fine and dandy up until now.
Odd Rendering:
To get SL to render things, you have to now aim in their general direction. While this may be intentional, it's bad for things like shopping in large stores. In the SIM I've been building in (Full empty sim), I have to spin around to get the mini-map to stop having blue chunks on it.
Physical not registering:
Only has happened twice so far, and only with mega-prims sent to over 800m. Anyhow, sometimes physical doesn't 'catch', as in the giant ball I made shows physical as checked, but isn't falling from the sky. If I uncheck-recheck it, it will register though.
=======================
Please, if you've found more problems, post them here so others know them, and post/vote on JIRA.
