Have had some reports from other tech writers that pages in CAC are not displaying correctly, and when you click in the page, it fixes itself.

Strange spacing between words and missing words was reported by wthompson. pwatson reports seeing similar behaviour. npye reports font size issues.

I have seen page headings display with incorrect fonts (fairly regularly).

jsoderstrom was able to replicate the behaviour by leaving a tab open for a long time, again it corrected itself when you clicked to switch focus to that tab.

Would be worth investigating if this is something specific to our custom CSS, or whether it affects any custom CSS in a space (and might therefore be affecting customers also).
