When entering text, the cursor tends to appear a few characters before the point where I’m typing. The number of characters in between varies, sometimes more than 10.
When moving a part of the schematic it jumps around wildly, but the amplitude of this jumping slowly decreases until the position is stabilized. I noticed a somewhat similar report (apr 2024) about component placement, not sure if its related.
This might be linked to a recent Qspice update or Windows update, I did not see this behavior one month ago.
