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 Paulo Andrade 2020-09-29 17:51:37 UTC
Steps to reproduce:

1. Start evolution
2. View -> Layout -> Uncheck "Show Side Bar"
3. View -> Window -> Choose "Calendar"
4. Edit -> Preferences -> General -> Week starts on: select Saturday
5. Create one appointment per day until filling the current week
6. Close the evolution window
7. Start evolution
8. Scroll calendar to not have the current day visible
9. Press Ctrl-T

It will enter a 100% cpu usage loop. Looping apparently on a very
deep call trace on gtk_css_node_ensure_style.
Attempted a gtk3 build with https://github.com/GNOME/gtk/commit/fc823eb61002d1350305cba6ec718a7c4f6c05e1
but it still consumes 100% cpu, just that does not create very deep
stack traces on gtk_css_node_ensure_style.

Comment 1 Paulo Andrade 2020-09-29 17:54:19 UTC
Ops, on step 4 should also select Saturday and Sunday as work days.

Comment 3 Milan Crha 2020-09-30 11:51:53 UTC
Thanks for a bug report. I can reproduce it too, but only in the Month View. Other views do not trigger the gtk+ bug (I suppose so, because the backtrace shows a long recursive call of gtk_css_node_ensure_style() function (more than 1000 of those on the stack). After some investigation, the gtk+ function call is only a side effect of a disagreement between the mini-calendar inner state and the actual settings, causing immediate change of the selected month due to "rounding" to correct time. Once this is fixed it all behaves as it should.

Comment 4 Milan Crha 2020-09-30 11:59:53 UTC
I fixed this upstream [1] for 3.39.1+ and 3.38.1+.

Comment 5 Milan Crha 2020-09-30 13:20:34 UTC
As a workaround, let the side bar shown at least once (press F9 twice). That's enough to make it work as expected.

Comment 9 Michal Odehnal 2020-10-19 09:43:59 UTC
Unable to reproduce with evolution-3.28.5-15.el8.x86_64. Switching to VERIFIED.
