@akallabeth It seems your recent comments have fixed everything. Thank you!
EnchantedHunter on Aug 1, 2023
@EnchantedHunter did create a pull request #9230 that should address this issue.
akallabeth on Jul 31, 2023
@EnchantedHunter that looks like you nailed it.
akallabeth on Jul 31, 2023
Hello, I think I managed to find a pattern. So there is a function rdpgfx_send_caps_confirm_pdu that sends 22 bytes to rdpgfx_channel, and there is a function rdpgfx_send_reset_graphics_pdu that sends 342 bytes to rdpgfx_channel. They are called in different threads and if rdpgfx_send_caps_confirm_pdu is called first, then the connection is established, otherwise the connection is broken.
EnchantedHunter on Jul 31, 2023
You are absolutely right, the problem is in rdpgfx.
