Duplicate Files List Flickering on Mouse Movement

Duplicate Cleaner Free 3.2.1

Duplicate Files List Flickering on Mouse Movement, sometimes.
Noticed it with a restored session, that when I would move my mouse over the file list, I would get flickering.

So I ran a new scan (re-ran the existing actually), then Quit, & restarted at which point I got the flickering again.

Then I switched away from Duplicate Cleaner, came back & at that point the flickering had subsided.
(That was not the case the first time I observed this.)

Perhaps the list is being affected by windows/objects outside of Duplicate Cleaner, bleed through or something or the other?
IOW as I'm composing this, the animated GIF open in my browser, Duplicate Cleaner at some point topmost again, & I then had terrible redraw issues from Duplicate Cleaner, my browser, & other apps. Not until I minimized all did normal drawing return.

Yesterday I did a defrag (JKDefrag) on my system drive, E:, not bad off as it was, & then on my C: drive, more beneficial there.
The defrag made no difference as far as the flickering was concerned.

Today "video drivers" popped into my head (old & reliable 6.14.10.5673 - nVIDIA ForceWare 56.73).
That made me think of "Safe Mode".
So I rebooted in Safe Mode (*it must be Safe Mode with Networking), opened Duplicate Cleaner & there was no flickering.
(Everything was huge, expected, & only a small portion of DC was actually viewable, but I didn't seem to have any issue.)

Restart in normal mode, opened Duplicate Cleaner & the flickering was back.


Later today I also updated my "codec pack" (CCCP), all the while thinking "video drivers", being somewhat akin to, audio & video "codecs" & "filters".


So after install & reboot, & now having a number of my typical applications open & running simultaneously, it looks like my flickering issue has righted itself.

Well that was short lived.
Opened up Duplicate Cleaner this morning (have had the computer asleep over the weekend), restoring an existing duplicate search listing, & the flickering has returned?

So it's not happening always, consistently, even during the same session, as it may flicker, I jump to something else, return, & the flickering has subsided, only to jump away again, & return, to have it start up again?

So something must be triggering it?
For a moment, I even thought something like "bleed through", where the animated gif on this page somehow affected Duplicate Cleaner?
