Pixel doubling issues with GTK3 and high-DPI displays #3

Open david-christiansen opened 8 years ago

david-christiansen commented 8 years ago

I have a laptop with a very high-res display, so GTK3 runs in pixel-doubling mode. When I run slideshow-latex, the bitmaps all come out blurry unless I turn off pixel doubling by setting GDK_SCALE=1 and GDK_DPI_SCALE=1.

I would think that the DPI setting for LaTeX should use my screen's actual pixels, rather than GTK's logical pixes in HiDPI mode.

Can you try to go to this line https://github.com/jeapostrophe/slideshow-latex/blob/master/slideshow/latex.rkt#L21 and change it to also multiply by (get-display-backing-scale) and see if that does it?
