Hi Everyone, I want to test whether 2D acceleration makes QtWebEngine (Chromium) reactive enough on the BBB. I tried Rémi's procedure, and I can run the OGLES2 demos and kmscube. However, when I try to use a QWebEngineView in a Qt application, I get a segmentation fault (other Qt apps are fine).
I checked with ldd that my app is linked with libgbm2 and not libgbm1, so that does not seem to be the problem. Has anyone tried QtWebEngine with this setup? Could it be that the debian package for QtWebEngine is incompatible?
