"Current Frame" window doesn't update after a few frames

I'm running ORB_SLAM3 in a docker container with an appropriate setup such that the viewer can function. The Map-Viewer window works completely fine, but the Current Frame window just won't show the current frame anymore after displaying a few images. Closing the window causes it to immediatly reopen, where again, a few frames are displayed. Has anybody else experienced a similar issue?
