X Error of failed request: BadRequest (invalid request code or no such operation)

[spuder]

This works outside of docker, but fails inside of docker

MYTMPDIR="$(mktemp -d)"
trap 'rm -rf -- "$MYTMPDIR"' EXIT
echo "Creating temp directory ${MYTMPDIR}"
filename=$(basename "$file")
echo "Basename: $filename"
docker run --rm -v $(PWD):/data -v ${MYTMPDIR}:/foo spuder/openscad:latest openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o '/foo/foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 3 --colorscheme 'Tomorrow Night' --viewall --autocenter

Cleaning the temp directory seems to fix it in atleast 1 situation (but isn't consitent)

May need opengl?

But I'm pretty sure I've had this working several times in docker before

Reducing the --animate to 3 works (sometimes)

docker run --rm -v $(PWD):/data -v ${MYTMPDIR}:/foo spuder/openscad:latest openscad /dev/null -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o '/foo/foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 3 --colorscheme 'Tomorrow Night' --viewall --autocenter --preview

Worked

    docker run --memory 2048m --oom-kill-disable --rm -v $(PWD):/data -v ${MYTMPDIR}:/foo spuder/openscad:latest openscad /dev/null -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o '/foo/foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 3 --colorscheme 'Tomorrow Night' --viewall --autocenter --preview

But running again immediately throws error.
Deleting $MYTMPDIR/*.png still throws error
Running again still throws error

Looks like this only happens when --animate >4. Opened ticket to figure out what is happening openscad/openscad#4028

Workaround:

By commenting out these lines in the entrypoint.sh and starting with a fresh $MYTMPDIR. I"m able to reduce (but not eliminate) crashes when > 3

# XVFB_WHD=${XVFB_WHD:-1280x720x16}
# Xvfb :99 -ac -screen 0 $XVFB_WHD -nolisten tcp &
# sleep 2
# export DISPLAY=:99

rm $MYTMPDIR/*; docker run --rm -v $(PWD):/data -v ${MYTMPDIR}:/foo spuder/openscad:latest openscad /dev/null -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o '/foo/foo.png' -D 'cube([2,3,4]);' --imgsize=100,100 --animate 4 --colorscheme 'Tomorrow Night' --viewall --autocenter --preview; ls $MYTMPDIR
