label-attribute-reftest fails on Debian i386: slightly different rendering in "e" and "r"
Steps to reproduce
Run reftests with GTK 4.0.3 on Debian i386. This was originally seen in an automated build but I was able to reproduce it in an autobuilder environment.
The current baseline for Debian's i386 architecture is i686 minus one instruction, so it does not have MMX, SSE or
-mfpmath=sse, and slight rendering differences like this might be to do with i387 floating-point excess precision.
- Debian unstable (rolling release) as of 2021-02-14
- GTK 4.0.3, no patches applied at the time
- Pango 1.48.0-1
- Cairo 1.16.0-5
- See the build log for full details of everything that was installed in the build chroot
