Seems like I was able to narrow down the bug with fonts fallback.
(Requisites: multiple fallback fonts for 'monospace'.)
Running on HiDPI with 'pixelsize' -- all works as expected:
st -f monospace:pixelsize=35
Using relative font size, only first font treats 'size' as relative.
But all consequent fonts treat that size like it's absolute:
st -f monospace:size=10
All fallbacks becomes the same as pixelsize=35:
st -f monospace:size=35
However, if after that I use <C-S-Home> -- fonts will be reloaded
and size for all symbols becomes correct.
Therefore dirty fix for such problem can be like this:
diff --git a/st.c b/st.c
index 2594c65..6529f56 100644
--- a/st.c
+++ b/st.c
@@ -4399,2 +4399,4 @@ run:
selinit();
+ xunloadfonts();
+ xloadfonts(usedfont, defaultfontsize);
run();
Truly speaking, after several hours of debugging I couldn't
understand what influences that behaviour. Maybe someone could
suggest where is problem?
P.S. Christoph, I would liked to see your fontconfig anyway.
Even if roots of this bug aren't there.
