Which is weird, in power saving mode (i.e. the dGPU is bypassed) the program
should run exclusively on the Intel HD 5500 here--suggesting the "4624" driver
is good for use on the iGPU? And instead it is the AMD dGPU R9 M375 that is
causing the visual glitches?

Which is not to say that we are not still doing something dodgy with our
DirectWrite/GDI interactions, we probably are, but how are open source cross
platform projects supposed to guard against system hardware/driver issues like
these?
