[chimerax-users] Drag select blanks view window

In ChimeraX 1.3 and now 1.4 releases, I have an issue where control-click dragging to select causes the 3D viewer frame to black out. Everything else functions normally, including the select itself, although it is very difficult to use since the structure can't be seen. The select box *is* visible, but it's magenta instead of green. Afterwards things go back to normal if something was box selected, but if nothing was boxed then the 3D viewer remains blacked out until an interaction like moving the models/camera takes place. I'm on a 2021 M1 MacBook Pro with macOS 12.4. I was wondering if others have experienced this and if it's an M1 issue as this is the only machine I've seen exhibit the problem. Best, -da
