RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
When resizing evo mail window, the leftmost column stays of the same size (good) but so do rightmost columns in Mail and Calendar views (message preview in with vertical view and tasks preview respectively). When the resizes aren't slight, (e.g. for 1600x900 <--> 1920x1080 screen resolution ), the settings can not be adjusted to fit both resolutions and most importantly, if you switch from one window size to the other and back, the layout is different than in the beginning.

The constant ratio in Mail should rather be width_of_variable_width_columns:msg_preview, if possible.

The bug in Mail view is a regression from RHEL 2.28, in Calendar view is a new bug.

Version-Release number of selected component (if applicable):
evolution-2.32.3-1.el6.x86_64 (from evolution-232-testing)

How reproducible:
always

Steps to Reproduce:
1. resize Mail window with vertical message preview (resp. Calendar window)
2.
3.

Actual results:
message preview (resp. tasks preview) has the same width as before

Expected results:
message list and message preview (resp. main calendar view and tasks preview) are resized in proportion

Additional info:

One slightly related upstream bug report:
https://bugzilla.gnome.org/show_bug.cgi?id=651633

Though not that much related, because the behaviour to stick with one side of the paned view and change only the other side was done more as a feature, than a bug. It was due to wrong restore when the GtkPaned used real percent sizes.

I keep the decision on Matthew, I would just WontFix this.

Those panels are supposed to stay fixed during window resizes.

Closing as NOTABUG.
