Hello,
I am using UltraVNC as a VNC viewer on Windows PC's.
Has been using it for years.

Since several months ago I am getting severe artefacts in KStars sky map when connected via VNC.
Using latest stable Stellarmate X OS on Mele.

it's not a very big deal but looks unpleasant.
Is this my VNC viewer problem or something else? Thanks!

I get this frequently with the latest nightly on Ubuntu 22.04 using NoMachine, going from my Mac to a MeLE Quieter 3C. Moving the displayed area and/or the zoom forces repaints that aleivate the problem for a bit for the affected overlay tiles.

I have similar artifacts using Stellarmate 1.8.1 running on an rpi4 and accessing from a Macbook using noVNC. My artifacts flicker and change. Very distracting.

I get the same issue with the Mac Version.

One suggestion is to use an HDMI dongle (dummy plug) so that your laptop thinks it has an active monitor connected to it. You can then choose 'real' resolutions and in my opinion the image transfer is faster.

Costs are only a few euros, so definitely worth a try.

First, it worked just fine not long ago.
Second, VNC resolution corresponds to Stellarmate's 1920x1080.

The HDMI dongle is not a solution. My setup is more or less the same than Jerry Black with a HDMI dongle, using NoMachine and I sometimes get the artefacts.

I have never used Stellarmate and don't know if it's using X or Wayland as window manager but that could maybe make the difference how the starmap looks like ??

Has there been any progress on resolving this? I still get these on my RPi running the latest version of Stellarmate OS v1.8.2 (I think). And there are times when the response is very slow even though both the RPi and my laptop are connected to the same home Wifi.

I get the artifacts on the skymap also using both Remmina and TigerVNC.
.
When using VNC over the Stellarmate Hotspot, the VNC connection eventually freezes up and the connection becomes unusable. This only happens with the Skymap over the Hotspot using any VNC program. .
.
If I connect the Rpi to my home network or the mount's handset's router via WiFi or if I plug an ethernet cable directly into the Rpi, then it works normally - with the artifacts.
.
If I can stay away from the Skymap and use only the Ekos and INDI driver pages, then the VNC connection over Hotspot works reasonably well. But once I go to the skymap then the Rpi side freezes and needs to be power cycled.
.
I believe this freezing is happening to only the graphics system since ekos and INDI still operate the mount and cameras normally. I just cannot access any controls. I can still SSH normally into the Rpi and run command line tools such as htop.

On both my Intel NUC 11 Essential and my BeeLink U59 I had numerous display issues (and even becoming non-responsive) with StellarMate X OS.

Once I disabled the Compositor under the Display and Monitor in System Settings I have no longer seen this issue.
I don't think this is enabled on the RPi version of StellarMate (haven't used it in a few months).
