Graphical display of lyx flawed

[Erich Minderlein]

Hi

If you're not sure whether it
really is a bug, you can e-mail the LyX developers' mailing list (lyx-devel
<at> lists.lyx.org) and ask.

Which I do now
I used to work with lyx, for a long time with debian, and now devuan.
A fresh new install of devuan daedalus and
Desktop Mate 1.26.0
and
lyx --version
LyX 2.3.7 (2023-01-01)
Configuration
   Host type:               x86_64-pc-linux-gnu
   Special build flags:      build=release std-regex warnings use-enchant
   Bundled libraries:       (none)
   C++ Compiler:            g++ (12.2.0)
   C++ Compiler flags:       -Wall -Wextra -fPIC -O2 -std=c++14 
-Wno-deprecated-copy
   C++ Compiler user flags:  -Wdate-time -D_FORTIFY_SOURCE=2 -std=c++14 
-g -O2 -ffile-prefix-map=/build/lyx-LshgcZ/lyx-2.3.7=. 
-fstack-protector-strong -Wformat -Werror=format-security -fPIC
   Linker flags:
   Linker user flags:       -Wl,-z,defs -Wl,-z,relro -Wl,-z,now
   Qt Frontend:
       Qt version:	   5.15.7
   Packaging:               posix
   LyX binary dir:          /usr/bin
   LyX files dir:           /usr/share/lyx

shows effects on the display, which make it impossible to work with.

May be a deb package is missing or some setting has gone mad.

see the screenshot of the open file menu, which has artifacts and white 
spots when scrolling with the up/down keys.

also mouse cursor selection seems to fail

aptitude show sgmltools-lite
Kein Installationskandidat für sgmltools-lite gefunden
Paket: sgmltools-lite
Zustand: kein echtes Paket
is recommended but not existing

I have these erroros when starting
lyx -dbg graphics
Format.cpp (127): New Format: n=lyxgz, flags=5

Lyx is not usable in this condition

pls advise : bug or something missing ?
