There is different space after textarea in Chrome, Firefox, Opera and IE
To fix this problem you need to add following to the css style of the textarea element
vertical-align: top
To do that you can use block IO debugging capability of Linux kernel.
echo 1 > /proc/sys/vm/block_dump
After this run
dmesg | egrep "READ|WRITE|dirtied" | awk '{print $1}'| sort | uniq -c | sort -rn | head
1583 kjournald(2764):
545 kjournald(1023):
48 beam.smp(21021):
47 sendmail(20992):
28 crond(20974):
Now disable the block IO debugging
echo 0 > /proc/sys/vm/block_dump
