I don't notice any difference in the lag time any more after updating qt6-webengine and my nvidia drivers. The system Sigil 2.5 (with Qt6.9.0) seems as snappy as the Sigil 2.5. AppImage (with Qt6.8.2).
I'm still getting this annoying when launching Sigil with the system Qt6.9.0:
Code:
Warning: GBM is not supported with the current configuration. Fallback to Vulkan rendering in Chromium.
I don't like it that I don't seem to be getting any hardware acceleration when using qt6-webengine-6.9.0. but it's not a deal-breaker by any means.
