[PATCH] ANSI background color malfunction

[Leo Savernik]

Ubuntu 22.04 LTS

In the latest konsole I noticed that ANSI background tinting stopped working properly:

\033]11;#320000\a

where #320000 can be any #rrggbb color code.

*Steps to reproduce*

1. Open fresh Konsole
2. (optional) Fill screen with arbitrary foreground content
3. printf '\033]11;#320000\a'

*Expected results*

Whole Terminal background is immediately tinted dark red.

*Actual results*

Terminal background stays black.

Only if terminal window is forced to be repainted, the background tint will show.

Fixed in Upstream Konsole: https://bugs.kde.org/show_bug.cgi?id=455554

Fixed in v22.04.0. There won't be further v21.12 releases from KDE
(https://community.kde.org/Schedules), but FWIW the commit that fixes this bug
(2f2ae3d9bb8a44fa987c10cc4b2a9018d34f300b) applies cleanly on top of v21.12.3,
so maybe the Kubuntu konsole package maintainers could backport it.

Please consider backporting to 22.04 LTS.
