It might work to drop a repaired "libpangocairo.so" into the "lib"
directory of your Racket installation. I'll see if I can build one,
just to see how hard that is. :)

You could set PLT_DISPLAY_BACKING_SCALE=1, but I think that won't help,
because Slideshow will still scale the content to match the screen size
(so it should arrive at the same overall scale factor).
Can you set your laptop's screen to 1024x768 resolution? Then there
would be no scaling. It seems like that might happen anyway when
connecting to a projector, but I don't know well enough how changing
the display works with Unix/X.
In another direction, you could disable kerning by adjusting your font
description to include 'no-combine:
(parameterize ([current-main-font (cons 'no-combine (current-main-font))])
(slide
(para "Types")))
