It is not useful to show such problems in 24.3, because the bugfixes I
lately committed to the emacs-24 branch are not there, so display of
hscrolled R2L lines there is fundamentally broken.

Yes, but that's an entirely different problem: looks like moving point
by clicking the mouse doesn't work correctly at all in hscrolled R2L
lines.  Please file a bug report, and I will fix this.

Hey, when I added bidi support, I did do a thorough job for the most
basic features, and mouse clicks are certainly part of that.
