Summary 08646: UI: BGFX: "None" bgfx screen chain returns to default value when switching to/from fullscreen
Description While the current chain is normally kept when going fullscreen, this won't be the case if it's set as "None", which will revert to the default chain specified in mame.ini.
Steps To Reproduce -When using bgfx, move the "Window 0, Screen 0 Effect" all the way to the left, to "None".
-Press Alt+Enter. The value won't be "None" anymore and the screen will reflect the new chain.
Additional Information Might be somewhat related to issue 8636.

 I started with this, but when I switched to full screen it crashed, probably due to MT8645. Not only that, the initial effect was hq3x which seems to have come out of thin air (my default is Unfiltered). After the crash, selecting the slider produced the correct Unfiltered without having to do anything.

So, after selecting None, you must press esc to get rid of the slider menu to stop the above crash. Now, pressing Alt-enter goes to full screen, and the slider has moved to Unfiltered by itself.

After a while, I tried all this again, and hq3x reappeared by itself as the initial value.
