Blue line artifact

SUMMARY
When there's a lot of fast-scrolling text in the Konsole window, there is a strange vertical blue line to the left of the text. It follows the text and randomly flickers.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.73.0
Qt Version: 5.15.0

ADDITIONAL INFORMATION
Does not happen in Konsole 20.04.3. Also happens in latest git master (40fd8e2a at the time of writing). Both systems I can reproduce this on are using AMD GPUs with the amdgpu driver.

Hi, I saw 2 bug reports about this new feature: what if we add something
like "What's new" similar to Chrome and Firefox DevTools have.

I don't know if we can highlight the *What's new* in the menu or a
notification when the first time Konsole is opened and the app was upgraded
from 20.08 to 20.12

I know about this page
https://kde.org/announcements/releases/2020-08-apps-update/ but it is not
visible enough.

it's not hard to add a "What's new" on konsole, but we need to do that in a way that every KDE also implement. 
I have a *really* old implementation of such thing "KWelcomeWidget" that I can revive.
