Setting rendering to default (Tools -> Options -> View unchecking Use OpenGL)
opening this Base document, and selecting Form1 which opens into Form edit
view.
On mouse over of the Text box its text will flicker, as will entering the Text
box and scrolling the text, as will selection of the text.
This is a rendering issue in refreshing the canvas, seems the same as bug
118856 for the Help -> About dialog. And the similar form design mode <a class="bz_bug_link

title="VERIFIED FIXED - Flicker when hovering over main menu with default rendering"
href="show_bug.cgi?id=113714">bug 113714</a> issue with Main menu, Miklos fixed that [1] adjusting from
direct RenderContext to use a buffer--effectively double buffered.
IIUC OpenGL and GTK3 rendering already does the double buffering, so they are
not affected.
Enabling OpenGL rendering (and verifying it took) the "flicker" will vanish--on
the Base Form1 view, and on the Help -> About dialog.
