Widget redraw problem

[Tristan Croll]

The following bug report has been submitted:
Platform:        Darwin-18.7.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-10-10)
Description
Some PyQt widgets seem a bit messed up on the Mac lately, causing some pain on ISOLDE's control panel. Specifically, arranged in vertical/horizontal layouts aren't redrawing properly when showing/hiding one of the widgets. For example, if I go to the Validate tab and click the "Show" button beside Peptide bond geometry then it looks like the expanded table has covered up the Rotamers and Clashes entries. It hasn't - they just haven't redrawn. If I click in the place where one of the buttons should have moved to, it turns out it's there. When I click on another window so the ISOLDE panel loses focus, *then* it redraws properly.

Seems like a (Py)Qt bug specific to the Mac... haven't seen the problem in Linux, but haven't tested in Windows yet.

Yep - seems Mac-specific. Working fine in a fresh Windows build.

Went to a newer version of Qt not too long ago (Sept. 19).

[Greg Couch]

To debug this if this is a problem with a particular version of Qt, you can pip uninstall the PyQt5-commercial and PyQtWebEngine-commercial packages, then install the GPL versions with pip install.

ChimeraX -m pip uninstall PyQt5-commercial PyQtWebengine-commercial
ChimeraX -m pip install PyQt5==5.12.3 PyQtWebEngine==5.12.1

ChimeraX's version of PyQt5 5.12.3 uses Qt 5.12.5, while the version in PyPi uses Qt 5.12.4. You could also experiment with the newest version of PyQt:

ChimeraX -m pip install PyQt5==5.13.1 PyQtWebEngine==5.13.1

[Greg Couch]

Switched the daily build to PyQt 5.14.1 with Qt 5.14.1.

Are you still seeing this bug?

[Greg Couch]

Current using Qt 5.12.9. Will be switch to 5.15.? after the 1.1 release.
