MediaPortal 2 Version: 2.2.1

Description
I've run MP2 on a few machines as client/server and just client, and it's UI is really fast.

Sweeping the mouse around, pressing a button on the mouse and getting an instant reaction etc.


However on my Win7 machine (multi-displays and GPUs, although all displays are on one GPU), MP2 is really slow in the UI.

If I sweep the mouse around over buttons in menus, they often don't get 'hit' with the rollover action, and if I press a button it may often be missed.
Sweeping up/down the menu in settings, I'll be lucky if I can get one entry to highlight.

However, if I just select my internet browser window with MP2 in the background, and then sweep around the menu, the reaction/response is instant on roll-overs etc.


I've tried duplicate displays and disabling a display (I've not yet tried booting without a 2nd display/GPU to test), but I've not had any luck in making this issue go away.
I've also forced MP2 to use a specific display as it's primary one, but no luck there either.



Is there any known issue for this? Or a setting somewhere?

Clearly MP2 is running like a rocket on my machine, but only in the background haha.


Thanks

Dave

Steps to Reproduce:
Install MP2 and enjoy the laggy UI. Put to the background, but interface with UI, and it's nice and fast.

THIS ^^^^^

I had MediaPortal 2.2.1 installed on my machine for months working fine. I ran sysprep to move my system to new hardware. Low and behold I have this EXACT same behavior. I have uninstalled MP2, reinstalled to no avail. Problem persists.

    Please try the render stats:
    • Press F10 to show render stats as overlay. Take screenshots when focused and not focused
    • Press F11 to switch between "default", "VSYNC" and "Max Performance" mode. Does it make a difference? Also take screenshots and post them here

    Digging a little deeper using Process Explorer, I found that the MP2-Client.exe thread state is set as Wait: Suspended when the window is focus and stuttery and unusable. When it is not focused the thread state is set as Wait:WrUserRequest. On all of other working computers, the state is always set as Wait:WrUserRequest whether focus or not focused.

    Now we just have to figure out why it's being suspended when we activate or focus the window.

    I decided to just completely reinstall Windows 10 because I couldn't find anything else giving me clues as to why this is happening. Well amazingly, it still doesn't work correctly on a fresh install of Windows 10. That means it has to be something with the hardware or drivers right? Any help out there? Hello? Is this thing on?

    I think it’s a driver issue of your graphic card. Is it a AMD or Intel processor? Have you tried to install another driver?

    It's an AMD GPU, I think I did try a newer driver. I didn't try an older driver though. I'll give that a shot and see what happens. I moved on to MediaPortal 1 in the meantime and it works fine.. Gotta say I prefer MediaPortal 2 though, so I still want to figure this out.

    Downgraded Driver to about 3 months ago. That would have been what I was using on my system before upgrading Mobo + CPU + Memory. No change.
    Also, used the AMD Cleanup Utility to completely remove Radeon drivers and used Microsoft basic video driver. No change. Any other ideals?
