Hi there!
1. Yes, it happened on smaller resolutions (windowed) and Fullscreen with 1920 x 1080.
2. Ah ok, so radius I understand ;)
3. I know. Strange, that it happened now. (Never happened to me before.)
4. Not any affect, so far I noticed. It works without the frame. It is just visually confusing. (Ok, I think I misunderstood. I often experienced it with Immolate - because I used it a lot. But it sometimes happened to others as well...)
5. New bug: (probably) Ability "Winds of decay" (what a fun name) is not adapting to the openings, it also goes through walls, trees, etc...
