I'm on windows 8
RAM = 8gb;
AMD RadeonHD 7850 ;
OCz SSD 120gb..
DxDiag.txt is added in attachments with SS step by step with Key to understand the timing below. I tried to simplify this explanation and demonstrate even though I did not record a video.
Everytime I click on the shop or after champion select and game loads up my desktop will turn black, as if the client is full screened and bugged out. When I finish any game, it's still blacked out or if I alt+tab out while game is loading and showing team composition I receive the same results. I can press ALT+TAB, if I hold alt I can see a perfect preview of the client and even people typing in the lobby after game or any movement on the client.
As soon as I click on the client or anywhere on the desktop while previewing with ALT+TAB, EVERYTHING goes black again except for my toolbar. Where start menu would be all the way to time/date is visible but anything else is black; even the my desktop photo.. I must exit out of client and restart client to rid of the black desktop error.
I have re-installed Adobe Air 3.5 and Flash and other Adobe products just to be sure. I've tried to repair client, even a full re-install. I've scoured the forums and google for similar issues with the black desktop. I can always find multiple issues sometimes the exact same problem; never a solution. It seems to me it's something that occurs when you click on the shop button or when it loads the actual game and puts the client to sleep or in background.
There's something in common between those 2 actions that causes a black desktop. Any assistance would be amazing, but I understand how busy you guys are with all the other bugs.
Screenshot Key: (Mouse over pictures to see name of pic, ie; Screenshot(1) or Screenshot(10) but I did post in chronological order)
1.) I clicked on the shop - Black Desktop with toolbar still visible (if I alt+tab to desktop)
4.) I can go to dashboard of Windows 8 from the bottom left of screen and view things perfectly like photo, store, weather.
7.) I can even pull up the sidebar for options through windows 8 bottom right corner menu.
8.) I was lucky enough to snap this SS right after I alt+tab to see and then before I could click, it took this SS
10.) After I clicked, it returned to black desktop, I right click on the League symbol at toolbar and can even see the menu after right click to exit client.
After Exited, Returns to normal function.
TEMPORARY FIX = CHANGE RESOLUTION in a custom game, and return it back to normal, every time you restart client you will need to do this.
