Comment 2 Graham Perrin 2020-01-19 12:04:43 UTC 
Juraj, is this bug still reproducible? 

If so: what are your system settings for application style and for window decorations?
Comment 3 Juraj 2020-01-19 12:28:21 UTC 
Yes I can still reproduce.

my settings ?
OS: Artix Linux
QT Version: 5.14
Falkon: Application version 3.1.99 (91612fcb) (but it should not matter because there were not drastic changes in this area)
WM: OpenBox
Compositom: compton > picon
WM theme: probably Carbon or some dark one (sorry too lazy to check this one)
Qt Theme managed by qt5ct
Qt theme engine: Kvantum
Kvantum theme: Fluent-Dark
Linux Kernel: 4.19.xx

To be honest it took me a long while to get Falkon to display that restore page.
Comment 4 Graham Perrin 2020-01-19 18:05:59 UTC 
Thanks. 

In my (FreeBSD-CURRENT) case I worked around the bug by temporarily changing: 

* application style to Oxygen; and
* window decorations to Oxygen.
Comment 5 bsduck 2021-06-28 17:13:30 UTC 
I can reproduce too.

How to easily get the session restore page:
1. Open a website in Falkon
2. Kill the Falkon process
3. Start Falkon again
