Backport recommendation for libkscreen 6.5.6

[Vlad Zahorodnii]

Hello,

We would like to suggest that distributions shipping Plasma 6.5.6 also 
backport the following commits to libkscreen:

- 
https://invent.kde.org/plasma/libkscreen/-/commit/2d9f9dc036be5b71f25c8e6e312a054611179295
- 
https://invent.kde.org/plasma/libkscreen/-/commit/c7bb277331c7990c1e2b4474f7672bc092246be3
- 
https://invent.kde.org/plasma/libkscreen/-/commit/b38af62125c49633237314191f58f229eeac9966
- 
https://invent.kde.org/plasma/libkscreen/-/commit/dd6e98968c272c5e222ac1734a12ef63909cda0f

They should help with preventing plasmashell from crashing due to the 
initial roundtrips taking too long.

Regards,
Vlad
