When I switch focus, e.g. by using Alt-Tab or activating another window with the mouse, G'MIC-Qt just hides itself for some reason. Not a serious bug but I can see it being annoying to people if they are making or reading tutorials and have to switch windows frequently. AppImage e8e7017, on Arch running KDE Plasma.
See https://stackoverflow.com/a/2322954. I can make it a standard window, but I think that'll be inconvenient for our Mac users, where G'MIC is a Cocoa panel. This does not apply to upstream G'MIC because that's always a standalone application. CC Iván and Halla for a decision on how to fix this.
Fixed in the next tarball rollup.
