On Windows10, after working on a document for a little while, trying to pan with the spacebar shortcut sometimes causes jumping to the left. While holding down spacebar, I try to pan to the right. Upon letting go, the document jumps not even back to the original area of vision, but even further to the left. This keeps happening the more I try (and keeps inching further left everytime). Note: this continues to happen even if I'm not holding down spacebar anymore. Any panning after the bug starts continues. Requires restart of application, but eventually happens again.
