Screencast_from_2024-08-06_10-01-50

Running gtk4-demo in a Fedora 40 toolbox (gtk4-4.14.4-2.fc40.x86_64) on a X11 system with nvidia driver.

I get those warnings when starting gtk4-demo:

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate
libEGL warning: DRI3: Screen seems not DRI3 capable
MESA: error: ZINK: failed to choose pdev
