Hello Keyan,
apologies for the delay, project deadlines demanded attention...

hmm, I haven't looked at what Qt's renderText does, but perhaps it's
drawing into the wrong buffer (i.e. the buffer swap happens before it
draws to the back buffer) or the buffer is cleared after renderText?

There is SimpleTextForeground (in Source/System/Window/Foreground) that
renders lines of text. If you need a more sophisticated HUD (e.g. one
that also has graphical elements) I'd suggest creating your own
foreground for it - borrowing text rendering code from SimpleTextForeground.
Cheers,
Carsten
