High CPU Usage

Follow
Stephan STEINER

Today I returned from my lunch break to find my computer fan blowing at full throttle.
Looking at Task Manager, I found that Rainbow was keeping 30% of my CPU busy, plus almost 60% GPU. 


It isn't the first time this has happened. I think it has something to do with display resizing. I have a Dell UP3216Q display (32" 4K running at 125% scaling in Win10 version 1709), and during long breaks I turn off the screen.
Not all applications like this. They get resized to VGA and then back when the screen is turned back one.

    Dear Stephan,

    may I ask you if you still encounter the same issue?

    To strengthen Rainbow robustness, some enhancements have been made since you published... and I see no sharing on that article. So it would be interesting to get an update ?

    Thank you for your feedback.

    Best regards,

    Nathalie
