I've noticed on occasions that the game does freeze when opening the Ground Track window, but it's temporary. It freezes for about 10 seconds, then resumes, displaying the ground track window.
For how long does it freeze, for you?

It never unfreezes.........I have to kill the program.

Tested on v2026.2..34.3656, Windows 11.

I do get a brief freeze on pressing F3 but only for a second or two. So this is still a thing in some capacity.

I get the lock up too when I press F3. I eventually get the "Kitten Space Agency is not responding. I've let it sit for about 3 minutes before I close the program.

I'm also getting this lock up. Every time I press F3, the game instantly freezes and I have to kill it manually.

KSA Build: v2026.4.15.4141
OS: Linux Debian 12
Kernel: 6.1.0-40-amd64 (64-bit)
Video Card: AMD Radeon RX 580 Series
CPU: 6 × Intel® Core™ i5-9600K CPU @ 3.70GHz
Memory: 32 gb

Edit: I kept the game open, and the ground track screen eventually opened in the time it took for me to collect that data. Now, even across restarts and no matter how high I put the settings, the window opens instantly and with no issues when I press F3. I am no longer able to reproduce this issue.

Probably AMD memory issues given what GPUs you have reported. The tracking station does load a large texture for the map.
