v15 Text entry dialog causes high CPU temperatures in Full Screen mode

Looking at the visualization of the dirty regions, the text echo box remains being continuously rendered regardless of that mode setting.

Also, notice that moving around the keys in that dialog using arrow keys on a keyboard results in some really weird and unnecessary dirty regions way outside the entire dialog. Ideally, it should only dirty the before and after key buttons, if I understand the dirty region optimization correctly for controls.

I think this dialog box needs a serious looking into as to how it renders as it appears to be seriously broken and inefficient in rendering especially on 1080p screens.

Not sure why this became more of an issue in Kodi 15 in my case. Never noticed the problem in Kodi 14 before.

I think you need to look how OpenGL works ... what swapbuffers is and that dirty Region is all we can do.

Reduce your refreshrate to 24hz, but from the looks you have a serious fan issue. Return the box and never try to play an OpenGL game ... This is what kodi is after all.

From what you describe even glxgears would kill your machine and this is also vblanked.

That said: if vblank is working, see the fps in debug overlay, nothing we can do for you.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.
