The fonts look great, it definitely looks more native in Gnome with Cantarell. The dead pixels are also gone for me too. I'm seeing 20.0.3 in the about with the 64 bit build FWIW.
The image functionality appears to work, but had some hiccups. For example, the option to change pictures with the mousewheel doesn't appear to work (no effect from the mousewheel). Image viewing also exhibits the same issues I see with video playback, which is probably to be expected since both use display view.
To summarize, the current state of the issues:
1) The OSD won't stay on screen for me (it either doesn't appear when I mouse to the top of the screen or it appears for a split second and then vanishes), and
2) The switch to display view doesn't work consistently with dual monitors. The current behavior (with images or video) is that it seems to "pick" a monitor to display on, ignoring which monitor MC is currently on. For example, If I have MC on the right monitor and double-click a picture it displays on the left monitor, and if I close display view MC is now on the left monitor. The good news is that this is better than the "split screen" video behavior I was seeing previously, and video is much more usable as a result (even if I can't pick the monitor). So that's definite progress.
Thanks for integrating images, it's great to be able to access images using Gizmo or JRemote from a linux server now
