It could be a font issue (for the tree graphical characters). Which font
are you using? and is emacs running in a terminal or in its own window?

Best wishes

Mark

I tried changing the font, but that did help. I am running emacs in its
own window.

Ok switching to ubuntu mono regular fixed the issue. So it is really
related to font. I don't know what changed. I always used inconsolata
and it worked before.

My guess is that incosolata does not have all the graphics characters,
so emacs drops to a different font when displaying them. For some reason
it is now dropping to some other different font and the display is
getting messed up.

I think what-cursor-position called with a prefix argument (so C-u M-x
what-cursor-position) tells you (amongst other things) the font under
the cursor.  For me, when using incosalata as default font,  the quarter
circles and arrow heads are in some different font.

I don't know what the fix would be if this is the problem but lets see
if it the problem first!

Best wishes

Mark

Yes that seems to be issue. For non working I have

             position: 158 of 780 (20%), column: 36
             
            character: ├ (displayed as ├) (codepoint 9500, #o22434, #x251c)

               script: symbol
               syntax: _ 	which means: symbol
             category: .:Base, c:Chinese, h:Korean, j:Japanese
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"

For working font i have
