App uses a lot of CPU when main window is open

I'm not sure if this is a bug but it's quite odd to me.

It does that even when it's not visible, as in hidden by another window on top of it.

However, when minimized, it's good, not using CPU.

Can you send me a screenshot of "About" window like this? Thanks.

Here you go.

Actually it's a lot less CPU intensive right now, hovering around 10%, instead of ~35-40% like when I posted.

This might be due to the fact that the machine is a remote one that I RDP into. At the time I created this issue, I remoted in in HiDPI mode. Right now I'm remoting in in LoDPI mode.

But again, minimizing its window will drop the usage to close to 0.

Oh it makes sense. The UI is GPU accelerated with DirectX, but I'm not sure how it's going to behave via RDP - I assume it needs to stream the window 60 times a second. Locally it's always close to 0. An interesting one to investigate.

@aloneguid Yeah it's definitely an edge case. Please let me know if I can provide more information for debugging purposes.
