Description jm.ouwerkerk 2018-06-03 15:09:13 UTC 
During startup Falkon attempts to load the following libraries:
 - /usr/bin/libEGL.so
 - /usr/bin/libGLESv2.so

On Debian these do not exist, not even as a symlink to a compatible .so. On Debian, the OpenGL libraries are located in /usr/lib/$machine-triplet e.g. /usr/lib/x86-linux-gnu and there may not be any symlink for compatibility so it is important SO versioning is honoured (i.e. there may not be any such thing as a libEGL.so anywhere on the system, instead there may be a libEGL.so.0 or something like it).

Additionally, adjusting LD_LIBRARY_PATH has no effect -- indicating that these paths may be "hardcoded" into Falkon.

That's QtWebEngine bug, and only on wayland (which you forgot to mention), so use xcb platform instead.

Thanks for replying so quickly. Just a question though: which upstream bug? This one: https://bugreports.qt.io/browse/QTBUG-65682?gerritIssueType=IssueOnly ?
