@superman & @john walker many thanks for the tips. I opened up the door last night and took out the window regulator to operate the window manually. It became clear that the window was getting stuck in the frame when it was half way down/up. Had to apply too much force to move the window up or down. (had already repaired the broken spring slot before but to no avail)
So I took out the window frame to verify the felt. The felt was in ok condition (minor pieces missing), BUT when I checked the frame curb or camber (to check if there was no tension between frame and window) I noted that the window frame close to the b-pillar was not bent with the same curb as the window causing the window to get stuck in the frame, hence the slow movement when lowering or lifting the window.
Had to manually bend the frame to the correct camber. This was in no means perfect as I wanted to avoid putting a dent in the frame. So long story short: window slides better up and down in the frame (not perfect but way better than before).
Thanks for pointing me in the right direction.
