The increasingly anxious shifting from leg to leg you go through when
you are desperate to go to the lavatory and the person you are talking
to keeps on remembering a few final things he want to mention.

I tried with network-manager as well as without and wpa_supplicant
directly, no change.
Also removing the module and reloading it did not help.

See above.
From what you posted earlier, I think your card is like my Cards 1
3, but the PCI ID will tell for sure. These tests were run with
commit 0a92aec2f22d of wireless-testing. There are some test patches
installed, but non of them affect rtl8192se.
I am running on top of default kernel git, will try wireless-testing, too.
Thanks a lot and all the best, and let me know what I can provide more!
