BGRAGraphicControl performance issue about bgracontrols HOT 5 CLOSED

On my computer with Wine, I get 67 FPS for TBGRAVirtualScreen and 30 FPS for TBGRAGraphicControl.
On Linux I get around 30 FPS for both.
I would say normally TBGRAVirtualScreen is faster because it is opaque (no background, no alpha channel). Though I am surprised by a drop to 10 FPS only.

I run it maximized on a monitor with the resolution of 1920x1200 with an i7 core processor on Fedora Core 27 64bit . I tried to set ColorOpacity to 255, but that did not make any difference.
When I draw directly to the TForm canvas, I get 47 fps.

And what about all the components, most of our components are graphic control based, they are slower than the custom control based ones too?

On my 2011 Mac is the opposite, it works at 30 fps maximized with bgragraphiccontrol and with bgravirtualscreen it drops to 16 fps maximized.

I close this, nothing can be done in BGRA side, is the LCL not BGRABitmap drawing routines.
