Bug ID: 506105
Summary: VNC connection freezes after some inactivity seconds
Classification: Applications
Product: kstars
Version First 3.7.6

Platform: Other
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
KStars clock interferes with VNC when connected using a hotspot.
I'm using an Arch Linux distribution -AstroArch- with KStars+Ekos+INDI
installed on a RBP5
I've enabled a hotspot to connect wirelessly and VNC -ran from a Mint
distribution- works as expected until I run KStars.
At that point, if there is an inactivity about 2-5 seconds, the VNC client
stops refreshing the GUI.
I can recover from that state if I either move the mouse oo press some key
before 20-30 seconds. If not, the VNC freezes and I need to close and open
again the VNC client -tested with TigerVNC and RealVNC.
If I run KStars with the 'paused' option, then no freezing issue is observed.
If then I turn on the KStars clock, the issue occurs.
STEPS TO REPRODUCE
1. Connect to the host's hotspot and open an VNC client
2. Run KStars and ensure the clock is running
3. Whait a few seconds
OBSERVED RESULT
If the KStar's clockk is running the VNC GUI freezes after some seconds. Moving
the mouse or pressing keys recovers from this state, but only if the inactivity
time is less than 30-60 seconds. After this, closing and restarting the VNC
client is required.
EXPECTED RESULT
VNC should refresh the GUI
SOFTWARE/OS VERSIONS
KDE Frameworks Version: 5.116.0
Qt Version: 5.15.17 (built against 5.15.13)
Linux/KDE Plasma: Arch Linux ARM (Xcb)

ADDITIONAL INFORMATION
If a wired connection is used, everything runs as expected. Also it works fine
when connecting to the wireless hotspot using a WiFi repeater.
Both x0vncserver, x11vnc were used with the same result.
WiFi powersave is off.
