My setup is a laptop with an external monitor connected through a HDMI cable.
If I set my laptop screen to off in nvidia-settings then plasmashell memory
consumption starts increasing with no limit.
This used to work in Plasma version 5.26, but stopped in 5.27. Interestingly,
setting my laptop screen to off in "kcmshell5 kcm_kscreen" instead switches my
laptop screen off but doesn't cause the memory consumption increase.
STEPS TO REPRODUCE
1. Do a fresh start of Plasma
2. Start nvidia-settings
3. Go to "X Server Display Configuration"
4. Choose your laptop screen under "Selection:"
5. Choose "Off" under "Resolution:"
6. Uncheck "Make this the primary display for the X screen"
7. Press "Apply" button
OBSERVED RESULT
Memory consumption of plasmashell keeps gradually increasing from around 200 MB
to my memory limits.
EXPECTED RESULT
Memory consumption of plasmashell should not start increasing.
