I have the same problem with an Asus 13.3 inch high-res netbook, a Signature Edition version (that is, bought from Microsoft itself and supposedly optimized) with Windows 10. I'm really surprised there isn't a fix for this by now. Does MS monitor this forum for issues that need to be addressed? If not, how do we report issues in such a way that they get noticed?
I'm going to go blind trying to use certain applications...
ooh... Wow, really? The issue still persists in W10? I've been wanting to upgrade from 8.1 for just this reason hoping that it will fix the problem but I have to backup all my files first which is a pain.
The good news is that 1, every time someone posts it pushes it to the top of the MS forums so if a Q posted more than a yr ago is constantly being pushed to the top hopefully someone from MS will take note, 2, there's almost 900 views!! You take the number of posts and add that to the views that's going to be over 1,000 people who have this problem soon.
So if anyone has this problem too, please reply so we can keep this topic going and up on top also to annoy the MS guy enough that this gets passed along.
I also would like to point out that in my 1st post it was just a Firefox problem but it's other programs as well. Also that some in browser video players seem to have updated so video controls are suddenly bigger, like Youtube for example now has much bigger buttons.
