Integral sign appears in the wrong location inside lyx-2.3.4

[Anand Rangarajan]

OS: linux (opensuse leap 15.1)
Qt version: 5.14.0

I compiled and ran lyx-2.3.4 with the configuration shown below. A problem
seen in Feb 2019 (
https://www.mail-archive.com/lyx-users@lists.lyx.org/msg108800.html) is
still present. When I attempt to write an integral within a math
environment as in

\int_a^b f(x)dx

the location of the integral sign in lyx is wrong. Screenshot and lyx file
attached. (The pdf looks fine.)
