            Bug ID: 376589
           Summary: Layout destroyed after clicking link with HiDPI
           Product: kmail2
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: message list
          Assignee: kdepim-bugs at kde.org
          Reporter: thiago at kde.org
  Target Milestone: ---

When clicking a link in an email in KMail, the message view layout is destroyed
and cannot be recovered unless you close KMail's main window and open it again.
This happens for *every* link, but only happens on HiDPI screens
(QT_SCREEN_SCALE_FACTOR=2 or higher).

This has been happening since the switch to QtWebEngine. It has never worked
with it.

Steps to reproduce:
1) close kmail (killall kmail to be sure)
2) from a terminal, open kmail in HiDPI mode: QT_SCREEN_SCALE_FACTOR=2 kmail
3) select an email that has a web link
4) click it

Expected results:
Browser opens and KMail window remains as it was before clicking the link (see
"before" screenshot)

Actual results:
Browser opens, but KMail window layout is destroyed (see "after" screenshot).
