White color sometimes?

[MatG-DK]

Hi there, i could use some help with a strange problem i have sometimes.

I use Mr. Grims Poison for Win 8.1, OldNewExplorer, Aeroglass (donated version) and Aero Glass Configurator 3.0

For an example, if i open taskmanager i like to see the window is black, like in first attachment.
But sometimes its all white, second attachment.

If i go change my theme to Mr. Grims Toxic for Win 8.1 it is black, third attachment.
If i change back to the exact same Poison theme where i have changed cursors, wallpapers ect. the window in Taskmanager is white again.
If i choose the standard Poison theme (with no changes like cursors, wallpapers etc.) the color in Taskamanager is Black, just as i like it.
But after some time, the color will suddenly change to white again and i can't tell what triggers the color change??

Has anybody else this issue and is there a fix that would help more than a few restarts?

Thx in advance

(did my best to explain, but feel free to ask if me to elaborate)

Got this from Mr. Grim a while back, I used to have the same problem on Windows 8.1 ...........

Information

Getting rid of white areas in themes after coming out of lock or sleep in Windows 8.1 Windows 8 loads defaults from [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors] after every lock/sleep/hibernate. Make a backup of that key, take ownership of it, and then delete that whole key (defualtcolors). Then you wont have a problem.

Don't worry, it works on Windows 10 too

I've found out that hibernate triggers the color change.
The second thing that triggers it, is that if i lock my computer with "WinKey+L" and open it again, it's white again.

Same thing goes for Windows 10

I've been wondering for a while now what you're using for Task Manager, that doesn't look like the normal application from the newer OS's. Here's how mine looks:

Maybe if you try using the default one with 8/10 it will work. Right now it looks like a Windows 7 one that's been skinned.

It's the Taskmanager that comes from the Theme/Extra folder in some of the custom themes.
But the picture of the taskmanager was just an example. It does it on all window frames..
This is the Win 10 taskmanager:

I see, I am able to reproduce this problem by SuperKey+L to lock the screen. Happens with other themes as well.

But isn't this a bug??
