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.

Comment 2 Milan Crha 2017-08-21 16:02:35 UTC
Thanks for a bug report. Apart of evolution, also other (many) core packages had been updated, one of them being gtk3. I guess what you see is an overlay scrollbar functionality, being enabled in gtk3 by default. This causes scrollbars being hidden until a mouse pointer hovers near the window edge, where they use to be. This can be turned off when an environment variable is set:

   $ export GTK_OVERLAY_SCROLLING=0

You can give it a try also when running evolution from a terminal like this:

   $ GTK_OVERLAY_SCROLLING=0 evolution

All gtk3 applications should be "affected", unless then disable it in the code, which I doubt of.

Is it it, please?

Comment 3 Andy Feldt 2017-08-23 19:02:44 UTC
No, a hover does not reveal the scroll bar nor does setting that environment variable.  However, I do believe it is due to a change in gtk3 since we also see this behavior (no scroll bar) for emacs.  Note that this occurs in the MATE desktop and the Cinnamon desktop, but not in the Gnome Classic desktop.

Comment 4 Milan Crha 2017-08-24 06:35:23 UTC
Thanks for the update. I'm moving this to gtk3 then, because it looks like an issue there, as you said. Maybe the theme being used has its part on this too.

Comment 5 Milan Crha 2017-08-24 07:56:37 UTC
I tried running evolution under MATE and there are many runtime warnings from gtk+ about theme parsing issues. I think the EPEL should be updated too, all the parts which depend on gtk3 (as you found Cinnamon and MATE as the first), otherwise I'm afraid it's undoable to correct this on the gtk+ side. I'm not a gtk+ developer though, thus I can be wrong.

Comment 6 Milan Crha 2017-08-24 08:13:13 UTC
Ah, I just wrote it and then realized that MATE is updated to 1.16.2 in EPEL, thus I updated my RHEL machine with it (from 1.14.1) and it didn't help. What did help was to change the Theme, in System->Look & Feel->Appearance, to Adwaita.

Comment 7 Andy Feldt 2017-08-24 17:42:49 UTC
Yes, I have verified that this solves the scrollbar problems for evolution and emacs and also solves an issue with the menu items at the top of at Terminal window where they had been squashed together.

Thanks!

Comment 8 Matthias Clasen 2017-11-10 20:42:11 UTC
Cinnamon and Mate are not part of RHEL.
It sounds like you've found a workaround by switching to a supported theme.
