Re: Font problem in 2-lines titles with cairo terminals

The distro I have installed is  Q4OS 4.7 (www.q4os.org). I began using 
it because it was said to require few resources and to run smoothly on 
rather old machines (mine is more than 10 years old).

I installed gnuplot 5.4.2 on another computer under Win10, and the font 
problem doesn't happen.

I suspect the cause of the problem is in the cairo or pango library, but 
I am not sure.

I was indeed able to compile 5.4.3, but without the terminals I use to 
use (wxt, pngcairo, pdfcairo), it is not very useful.

Thanks anyway for all your help :)
