#6341 (Bug) New version of profile loader causes stuttering of mouse pointer / video playback (Windows)
I just updated to the latest version of DisplayCAL two days ago and I noticed the the mouse pointer stutters about every three seconds, supposedly happens every time the profile loader is trying to check the calibration loaded.
The problem with the mouse pointer is quite subtle, and I only became aware of it when I was playing games, or I move the pointer at a constant medium speed against a dark background while watching closely. The stuttering of video playback is more obvious, especially during panning scenes.
Before the update I was using version 3.1.7.x (can't remember which one exactly), and there were no stuttering issues at all. Turning off "Preserve calibration state" also fixes the issue.
I can replicate the issue on both of my Windows laptops. Both are running Windows 10 with recent patches, also graphics drivers (Intel and Nvidia) updated within a month ago (I actually saw the same issue with f.lux, and on their website they suggest updating the driver of the graphic card to fix the mouse pointer stuttering...but it didn't fix it for me).
I updated DisplayCAL just because I found the profile loading bug in the old version when there are multiple displays, and it's really nice that now the loader has an elegant profile association interface and has the option to fix profile association (the way Windows handles this is just confusing and often blatantly wrong). I would understand if changes have been made in the new version is really necessary, and I can live with adding certain programs to the exception list, e.g. video players and others which require high precision of mouse pointer. But I think it's probably worth reporting the issue here.
Best regards and thanks for the good work over the years!
