<br>
As Bert noticed a few weeks ago, fast-drag is kind of slow on MacOS.<br>
<br>
Today, I noticed under Windows that there is an occasional, GC-like lag when<br>
resizing windows with non-fast drag.<br>
<br>
Here is the Trunk (Cog) with noticable lag:<br>

Here is 4.6 (Cog) without lag:<br>

The drawing code in Morphic has not changed. I suspect an issue in the VM.<br></blockquote><div><br></div><div>You can get information on GC pause times by using the About Squeak inspector and looking at the information there-in.
