What steps will reproduce the problem?
1. Start aLogcat
2. Wait for some log messages to appear
3. Scroll

What is the expected output? What do you see instead?
I do see the expected output.
But aLogcat also shows a lot of these logs:

11-22 10:53:49.232: DEBUG/dalvikvm(353): GC_EXTERNAL_ALLOC freed 39K, 56% free 
2708K/6151K, external 3584K/3600K, paused 39ms

This makes it hard to follow the other logs.

What version of the product are you using? On what operating system?
aLogcat v2.3.2
Android v2.3.3
Desire/AndroidEmulator

Please provide any additional information below.

This makes alogcat almost unusable. Every time I scroll the window gets flooded 
with GC_EXTERNAL_ALLOC statements. 

Sometimes it'll get stuck and completely flooding the screen after I stop 
touching it. It has literally filled the entire scrollable area with those 
messages a few times.

Samsung Galaxy Tab
Android v2.3.5
aLogcat v2.3

Preface:  I am in no way associated with aLogCat development.  I just happened 
to stumble upon this issue.

This is not a defect in the logger and a filtering option is provided.  The 
following procedure will remove the garbage collection log entries from your 
aLogCat output:
1) While in aLogCat, press the Menu key on your device and tap Filter
2) Tap the check-box next to "Apply as regular expression?" to enable it
3) In the text box input the following exactly:  ^(?!.*(dalvikvm|GC)).*$
4) Tap Okay and your screen will be updated sans garbage collection spam.

Android is (very) new to me so I don't know if this is the perfect solution 
but...
Lets give it a try.

I think the background of the listview is the problem.
As explained in the following resource.
http://developer.android.com/resources/articles/listview-backgrounds.html

Removing this code from log.xml enables cacheColorHint optimization.
android:cacheColorHint="#00000000"
By enabling this optimization the garbage collection is drastically reduced.

The default cacheColorHint is black so we need set the cacheColorHint to the 
desired value. I did this by adding this line to the onStart() method of 
logActivity.java.
mLogList.setCacheColorHint(mPrefs.getBackgroundColor().getColor());
