Both mouse and tablet, inutos pro m 5 and it happened with either. I have used a few but I mostly use OBS. But the issue happens with all of the screen recording apps I've tried, such as Snagit. It's been happening more with OBS since I also do livestreams on sites like Picarto. It's actually still keeps happening sometimes with the most current release of 1.7 but it was also doing it in 1.6 only the cursor disappears completely in 1.7 now if I am specifically using a type of livestreaming recording app like OBS or XSplit. Unfortunately I don't save my videos and I'm not a popular streamer so the sites I stream from also don't save my videos. I will keep it in mind next time and upload a recording of the issue.
It seems to happen more if I leave the canvas to do something simple like colour pick, change layers with my stylus or mouse, or even if I change brush. If I am recording the brush reverts either to mouse cursor or fully disappears.
