Thanks for the report. Since showing text is proven to still work (as seen in the screenshots) I suspect the app is no longer receiving the (simulated) keypresses, because otherwise it should show at least the colorful "m" letters (even if rendering pictures would stop working for some reason).
To fix this, I need to figure out a way to interactively run the app against the new version of the library without messing up my (Debian stable) system... I'll try running it under xvfb in a container, but other ideas most welcome :-) Marcin
