I haven’t experienced it on my laptop either, it’s only on my desktop that I have this issue. Are you using the software that came with the mouse (SteelSeries engine 3?). Could that potentially be the cause?
I’m not sure what else could be causing it at this point, either some weird driver related issue (but I reinstalled my mouse drivers), or my Studio just being completely out of wack somehow (but I also tried reinstalling Studio).
Do you have any tips?
I also have another problem related to Studio that started happening around the same time, where I get a 1-second delay between clicking on Parts and selecting them:
Which also looks a lot like a problem from October 2016:
The microprofiler in that thread looks a lot like mine, “Ogrewidgets” and “Ribbonbars”.
All in all I have a lot of problems with Studio on my desktop and re-installing doesn’t seem to help
