The conditional format problem (item content disappears under the color) happens when the "#" column is visible in the grid screen. That's it.

 

When a slight horizontal scroll is performed to completely hide the "#" column, everything is perfect. (So, in the mean time, I just hide the # column whenever I don't need it.

 

Pierre : maybe you could send that description to the grid component provider ? (As this is a very un-user-friendly bug, and conditional formatting is and extremely convenient and powerful tool and should be used more in the sample DB)
