Summary0006149: Quick loading graphics glitch
DescriptionWhen quick loading, the screen usually flashes a little brighter and shows something odd for a brief moment before and after the loading screen. I had trouble seeing exactly what it was until I recorded it.

Frame by frame there is a regular view, what looks like some sort of view where objects become translucent, the loading screen, a translucent view again, and finally the regular view.

Fixed in svn rev 10182.

The greatest problem here was to catch the moment of the issue and find at least some location where things go wrong.
In the end, I used apitrace: I captured full history of GL commands, then replayed up to various moment in something like binsearch, until I found where the issue is.
I wonder if RenderDoc has the same capability...

The problem was inside StartWipe + CompleteWipe, which is called during game load.
The first function initializes wipe sequence, the second one renders frames of wipe sequence until it is over.
StartWipe was filling backend command buffer, but did not render these commands, so they were continued by the first frame of CompleteWipe.
It turns out such "double" frame does not work well: FBO state is wrong when rendering the second part (guiFBO attached for some reason).

I simply added R_IssueRenderCommands + R_ToggleSmpFrame, so that StartWipe commands are executed immediately.
This fixed the problem.
