Can't be a corrupt Filesystem, I've had this happen since a clean install, mostly dealt with it before coming this way. I've also reinstalled multiple times due to multiple HDD failures in a row (such luck) The glitch has also happened on the previous Installations as well. All win 7 x64 Professional, same with my laptop before I updated it to win 10, which so far hasn't seen this issue. Aside from WB and Iconpackger, I'm running pretty much vanilla (as in no UXTheme Patch) with Games, usual utilities and stranded files salvaged from a Dying HDD.
This "mis-alignment" only happens on certain windows, as in the screenshot, only Explorer windows were affected. firefox was perfectly fine. When it breaks, it's only that side that does. the buttons still function normally. At this moment using it, everything is fine. I believe it only occurs after Resume from Hibernate, quitting a game, resolution change, etc etc; It catches me off guard.
If the issue bothers me enough, I'll see what Support can do. for now, if none of y'all are having this bug (should see if an update is available)
Info from the "About" section if anyone's interested
Windows 7 Professional (7601.win7sp1_ldr.170209-0600)
WindowBlinds 10.62 (044 - Windows 7 Edition) - 64 bit OS
No updates currently as of writing this.
Sorry if I don't make much sense.
