[chimerax-users] Drag select blanks view window

[Tom Goddard]

Hi Daniel,

  On my 2022 M1 MacBook Pro with macOS 12.5 drag select on an atomic model shown as ribbon works correctly, never blacks out.  It sounds like a graphics driver bug.  I have been amazed that I have not seen any graphics driver bugs on Mac M1, nor have I seen any crashes, in the 1.5 years they have been out, while Intel Mac graphics drivers crashes often -- we get crash reports every week.

  You could use ChimeraX menu Help / Report a Bug so we get your exact system info.  But I'm not sure we are going to be able to do anything about that.  Maybe try updating to macOS 12.5 -- I doubt that will fix it, since I did not have your problem on macOS 12.4.

  You could also try the native M1 ChimeraX technology preview build at the bottom of the ChimeraX download page.

  Elaine in our lab has an older 2021 M1 MacBook Pro and I'll ask her to try drag select to look at if the structure disappears.

	Tom

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.
