The structure of the library names on the last release of Mesa that we ship now on the flatpak SDK has changed a bit. There are now newer libraries that required like libdrm* or libgbm* and also some other libraries have unchecked suffixes like libEGL_indirect.so.0 (we are currently only checking for suffix _mesa like in libEGL_mesa.so.0) This means that the syslibs-all bundle generated from the flatpak SDK misses some libraries from Mesa that make it crash when trying to enable the accelerated composited paths in some cases.
