Hi, Cygwin/X crashes every few days for me. I managed to obtain a backtrace from the last crash (attached). Server log is also included.
I have not, yet, managed to pin down the exact trigger for the crash. I am running two graphical programs under Windows 10 WSL2 Debian: tilix and evince. Thank you for any help. Best, Henry
