Bug ID: 356723
Summary: Incomplete window updates after updating to Plasma
5.5.0
Product: konsole
Version: 15.08.3
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: chemob...@gmail.com
After updating to Plasma 5.5.0 konsole window updates are incomplete. When
konsole starts to scroll only the lowest 2-3 lines of text (and some random
lines above) are updated. To get the real current content of the konsole
window, you have to click outside the konsole window (deactivates window) and
click on the konsole window (activates window again).
NOTE: konsole was not updated when I received the Plasma 5.5.0 update. So this
issue might be related to Plasma changes. But as far as I can see only konsole
has issues with window updates. I updated now to konsole 5.12.0, but the
problem is still there.
Several other people I have discussed on IRC with have also noticed this issues
on their system with different HW and open source drivers, so this is not an
Nvidia issue. I use a Dell laptop with Nvidia blob driver and describe how I
can reproduce this on my system.
Changing compositor settings or disabling compositor completely does not fix
this problem.
Reproducible: Always
Steps to Reproduce:
- laptop out of docking station, i.e. one screen only
- login to KDE session
- force scrolling in konsole sessions, e.g. commands with many lines of output
-> window updates are OK
- put laptop into docking station, switch to 2 external screens
- force scrolling in konsole sessions or scroll konsole window
-> lowest 2-3 lines are usually updated, randomly some other lines too
- switch back to 1-screen mode (laptop display)
- force scrolling in konsole sessions or scroll konsole window
-> issue is still there
