Thank you! This issue made me continue working on CS5.5 until now !
However, turning off the Cache indicator make disappear of course the display of the green/blue bar of the RAM/Disk preview. Viewing it can be useful. Any suggestions?
I’ve had this kind of problem for ages, but only with shape layers (works fine with solids)
I fixed it just by deactivating the Adaptative Resolution. Not ideal but it worked. Not exactly the same problem as the one described here, but it might help..
