  • Is Windows crash reporting ever useful? Should we disable it? Will Qt 6.2 fix spurious file dialog errors?
  • Should we remove pywin32 (20 MBytes) and wmi used only to report computer model in bug reporter on Windows? Ticket #5528
  • Task termination at app quit

• Action items

Discussion

• Qt 6
  • Greg suggests we us PyQt6 licensed wheels with PyQt6-Qt6 PyPi bundle that provides the Qt libraries.
  • Currently we instead bundle Qt6 with PyQt6 ourselves into a single wheel.
  • Would be simpler if we did not have to bundle.
  • Greg will try to make the change today or next week.
  • Qt 6.2.4 has come out and will be easy to put in daily builds with this change.
  • Zach says 4 ChimeraX Qt tickets are waiting on a new Qt version to fix them.
  • Qt 6.3 is supposed to release April 12

• Qt 6 for CentOS 7
  • Tests with singularity show Qt 6 won't work with CentOS 7 because newer system calls used by Qt 6.
  • This will also prevent FlatPack and Docker images from working.
  • Plan is now to make ChimeraX 1.3 (Qt 5) the last CentOS 7 release.

• VirtualGL
  • Commercial license holder reported ChimeraX not working with VirtualGL 3.0
  • Greg says this is because it is trying to use an EGL context, and bug report should be made to VirtualGL.
  • Possibly older VirtualGL 2.5 or 2.6 will work, and bug reporter will try that.

• Linux Wayland replacing X11
  • Greg says some most recent Linux distros are trying to make Wayland the default instead of X11 which requires using EGL for our OpenGL graphics.
  • Qt 6 is supposed to support EGL.
  • ChimeraX uses PyOpenGL and may have EGL support.
  • We may need to look into EGL for ChimeraX 1.5 or 1.6.

• ChimeraX 1.4
  • Goal is to release in May.
  • Original release date was April 1, but we are trying for May 1.
  • All features should be in within 2 weeks for a release candidate.
  • Still hoping Python 3.9.11 stops the 5 bug reports of day on Windows Open dialog crashes -- so far none reported in 3.9.11 but only out a week.

• Fire alarm
  • Building fire alarm ended meeting early.
