Windows 7: Corrupt application windows

Seeing some strange behaviour from multiple applications. Interacting with them gradually results in the window becoming corrupted.

At first it was just JDownloader, but now Thunderbird is doing it too (after a 3->5 upgrade). What is interesting is that any child window or dialog inherits the corruption, even on a different LCD screen (I have 2).

I thought it might be a video card issue at first, but only these 2 applications are affected.

Another interesting piece - if I run the 64bit JDownloader binary, it does not get corrupted, but the 32bit one does.



Compatibility mode doesn't seem to make a difference in either application.

This sound familiar to anyone? I'm at my wits' end. See attached screenshot for an example.

Welcome to Windows Seven Forums.

I think your computer has been hit by a virus.

Download Malwarebytes and run a full scan in Safe Mode.

I wish it was a virus, I could easily do something about that My Uni has a symantec site license, so I've been running with that for a while.

Any other ideas? It really seems to be something related to 32bit applications - I'm pretty sure Thunderbird 5 is a 32bit binary, as is the JDownloader binary that gets corrupted. The 64bit JDownloader exe does not exhibit this behaviour.

You'll need to seek help in a Java forum for that one.

If only people would run native programs, I personally hate the Java runtime, its really slow and buggy for applications, even though in theory it is great (works on MANY OS', Windows, Mac OS X, Linux, Solaris, Android, Symbian ect.).

Unfortunately this is occurring with Thunderbird as well. JDownloader is just one example.

It isn't Java, since I uninstalled both 32 and 64bit JREs and Thunderbird still exhibits this behaviour.

Here's Thunderbird doing the same thing. Unless it is shipping with an embedded jre/jdk, this isn't specifically a java isssue.

Bueller, Bueller, Bueller?

Just run a MalwareBytes scan. MalwareBytes is a very powerful AV on-demand tool compared to other AV's.

Nothing from any Malwarebytes scanner - I even booted up Trinity rescue kit and ran those AV scanners. Nothing.

Again, this seems to be a 64bit Windows vs. 32bit application issue.
