utf-8 thai character display issue? |

I am sometimes having trouble with displaying and entering a specific
thai character ำ "THAI CHARACTER SARA AM".
If that character follows some other thai characters or I try to type it
in directly following some other thai character it won't display
properly in the buffer. It looks like there is no character there.
I know actually it is in the buffer because I can get the properties of
it even though it is not being displayed. Here are 2 example words that
have issues on my system
กำลัง (ing)
น้ำ (water)
The 2nd word is always not displayed correctly. The first word is
sometimes displayed correctly depending on what other thai text files I
may have visited early. I have tried using and switching various thai
fonts and sizes, but it seems like once the issue appears changing or
resizing the fonts never helps.
My emacs version is
GNU Emacs 26.3 (build 1, x86_64--netbsd, GTK+ Version 3.24.14) of
2020-05-31
I also use this version of emacs built on macos and it doesn't have the
problem.
Here is the char info for it when it didn't display:
C-x C-u = gives this:
position: 285 of 365 (78%), restriction: <36-366>, column: 10
character: ำ (displayed as ำ) (codepoint 3635, #o7063, #xe33)

Here's for one time it was being display correctly:

display: composed to form "ำ" (see below)
Composed using this font:

by these glyphs:
