We just figured out the libGL error: MESA-LOADER error on el9, you can fix it by doing: ```LD_PRELOAD="/lib64/libLLVM-17.so" cmsShow ...``` see https://cms-talk.web.cern.ch/t/phase2-geometry-visualization/41531 We run Fedora 39 (me) and 40 (Alja)...

Hmmh, the actual crash seems to be in `void tbb::detail::d2::concurrent_queue::internal_push(mkfit::MkFinder* const&)`, apparently in a deleter here: https://github.com/cms-sw/cmssw/blob/master/RecoTracker/MkFitCore/src/Pool.h#L37 happening via release here: https://github.com/cms-sw/cmssw/blob/master/RecoTracker/MkFitCore/src/MkBuilder.cc#L950 There is a to-do note in MkFitProuducer where...

Sergey, all good questions, thank you :) > 1. Do we need to include all these fonts into ROOT repository? Font files are big and used only via random generator...

OK, I force-pushed a new version, now there are no SDF fonts in the repo -- but I have added two ttf fonts that have all the accented and greek...

Sergey, semi-related, have been running with valgrind (root supressions on), and this came up: ``` root [1] ==975849== Thread 8 civetweb-worker: ==975849== Conditional jump or move depends on uninitialised value(s)...

Yeah, they probably do some quirky simd stuff in there :) I realized yesterday that the stuff for creation of sdf textures always puts them in $ROOTSYS/ui5/eve7/ ... which will...

OK, I've moved png-writer to asimage. All that remains from my side is to figure out how to handle the case when $ROOTSYS is not writable -- see my comment...

Hmmh, but then I'd need to stream path information with every REveText object, now only the font name is streamed. It is indeed a reasonable thing to check if the...

Hmmh, so you don't want to give me an active directory? :) This could be really useful for accessing large tables per-partes ... or pre-processed parts of geometry, you know...

OK ... done. I have used THttpServer::AddLocation() to register sdf-fonts/ to either $ROOTSYS/ui5/eve7/sdf-fonts or ./sdf-fonts. One can also specify the location manually through REveText::SetSdfFontDir().
