Does not run properly on the Trimui

[Ultrahead]

After compiling with the proper toolchain for the Trimui, using ...

UNION_PLATFORM=trimuisp make

... the program outputs the following and generates the SimpleTerminal app in the build folder:

st build options:
UNION_PLATFORM = trimuisp
PREFIX         = /usr
CROSS_COMPILE  = 
SYSROOT        = 
CFLAGS   = -O2 -Os -Wall -I. -I/usr/include/SDL -DVERSION="1.0.1-a04cab6" -D_GNU_SOURCE=1 -D_REENTRANT  -fPIC -std=gnu11 -flto -Wno-unused-result -Wno-unused-variable
LDFLAGS  = -O2 -lc -L/usr/lib -lSDL -lpthread -Wl,-Bstatic,-lutil,-Bdynamic -s
CC       = gcc
SRC      = src/font.c src/keyboard.c src/msg_queue.c src/st.c
VERSION  = 1.0.1-a04cab6
mkdir -p build
gcc -o build/SimpleTerminal src/font.c src/keyboard.c src/msg_queue.c src/st.c -O2 -Os -Wall -I. -I/usr/include/SDL -DVERSION=\""1.0.1-a04cab6"\" -D_GNU_SOURCE=1 -D_REENTRANT  -fPIC -std=gnu11 -flto -Wno-unused-result -Wno-unused-variable -O2 -lc -L/usr/lib -lSDL -lpthread -Wl,-Bstatic,-lutil,-Bdynamic -s

But when executed on Trimui rendering is not ok (see screenshot) below:

Any help here will be appreciated.
