I have a laptop with arch linux, and a PC running Windows 10. I am trying to run pulseview on Arch, and then show the pixels on the windows PC. On the arch linux laptop I run sshd, and on the windows PC I run Xming and putty
Pulseview works fine when I run it locally on the Arch laptop.
Pulseview crashes when I resize the window. When I zoom in and out in pulseview with the scrollwheel, I see sshd taking up 25% of CPU on the laptop. This also happens when I move the mouse in the pulseview window. I see a framerate of about 3-5
I use the following settings in putty to connect to the laptop. All other settings are default
host name or address: 192.168.178.129, port 22
connection-ssh-X11-[X] X11 forwardingI see the following errors when I run pulseview via ssh:

MESA: error: ZINK: vkCreateInstance failed (VK_ERROR_INCOMPATIBLE_DRIVER)

When I enable compression in Putty the window of pulseview reacts smoothly, with a 0.3 second delay to the mouse. A big improvement over the 3 FPS of the alternative. on the laptop I now see 100% CPU of sshd when i continiously scroll with the mouse wheel.
I wonder if I have not enough network bandwidth between the laptop and desktop. The laptop is connected via wifi (module ath9k, 150Mbps), and the desktop is connected via ethernet cable.
Without compression, I see 70Mb/sec coming into the windows laptop when I scroll the mouse.
With compression I see about 3.5-4.5 MB/s coming into the windows laptop when I scroll the mouse.
The laptop has 100Mbps LAN, so there's no point in trying with an ethernet cable.

When I run firefox via ssh with compression enabled, I can resize and maximize the window without any issues. Firefox also doesn't give any messages on the console. What's different between firefox and pulseview?
