Extreme performance issues while taking screenshot

[LeonardBaranski]

Please include the following information:

vncdotool version 1.2.0

VNC server and version TightVNC -> version unclear

Steps to reproduce

• def run_vnc(): client = api.connect("localhost", password="password")

  client.captureScreen(f"screenshot1.png") print("Test") client.captureScreen(f"screenshot2.png") print("Test2") client.disconnect() run_vnc()

• we are trying to get a screenshot from a vnc device.

• the first screnshot returns just a black screen

• the second screenshot takes around 135 seconds every time, But returns the expected result.

• Why does it take so long to take a screenshot?

Additional information Furthermore the programm does not finish the process. The process is stuck and never gets finished.
