Rather minor issue, but issue non the less. Feel free to delete if duplicate.
Repro:
1. Open Research
2. Select a Tech that will have a scroll bar (like Civilization -> Mining, Warfare -> Standing Army)
3. Scroll the text down
4. Select the same Tech again
Observe that the scroll bar itself will jump to the top but the text won't.
Notes:
1. Screen res: 1920*1080, ATI Radeon 3850, Win XP
2. It's a clean Tutorial game where I encountered the issue, but it's probably common.
