Bug Description
When using the viewer in full-screen mode, the screen often blinks (sometimes for no reason I can see, I can sometimes get it to blink when I move the mouse pointer between the text area and the margin, opening or dismissing the menu makes the screen blink almost every time, as does switching to or from the viewer - for some reason, Alt+Tab dialog also isn't visible when in full-screen mode and Calibre Viewer is the active window; moving through Preferences also often makes the screen blink).
Additionally, mousewheel scrolling only works when mouse pointer is above the text area - if I move it outside, it's ignored - this is a regression from Calibre 3.
Also, Preferences → Page layout → "Change maximum screen area (in pixels) used to display text" option is misleading, since the setting definitely isn't in pixels, but instead appears to be scaled by screen DPI factor (I'm using a high-DPI display).
OS: Windows 10 1903 x64
Calibre: 4.2 64-bit
One more problem: if you switch away from the viewer (in full-screen mode), it'll change whatever it's showing with something it was showing earlier (this also happens if I move focus to a window on another monitor, just leaving the viewer where it was, with no other window obscuring it).
