Your change surely had something to do with the bug, still it was not a perfect fix. The active panel gets messed up not so easily now and it even seems that it gets messed up less visibly
... but the problem still happens
As usual, the way I reproduce it is:
Step 1. Go to the /Library directory
Step 2. Select a directory that is in the upper part of the listing (Colors or Frameworks)
Step 3. Scroll to the bottom of the listing using the wheel or scrollbar (careful not to change the selection)
Step 4. Hit enter ... and voila, it's quite often messed up
Step 5. Start navigating down in the folder to see the listing become good line by line
The bad results are now of three kinds:
1. Most of the times almost imperceptible overlapping that makes the text look bold. This did not happen so often before last night, and it probably it is better than the very visible overlappings happening very often before. Screenshots: Step1&2
(do you see the difference between the last two pictures?). One more example
2. Some times (but apparently less frequently than before) the usual totally messed up panel
, caused by some sort of bad overlapping.
3. Some times the contents are just partially duplicated and perfectly overlapped at first
, and it's hard to see until you start navigating
, or unless you really know the contents of your directories very well. Still, this is very annoying since a user might just panic over missing files or directories.
