For me 1.9.0 has video issues too. While moving my mouse the whole windows seems to flip upside down and back, for me it is almost unusable. Still checking if there are any driver updates available (intel igp). Hope this get fixed
Edit: I took the time to make a screenshot, this is when i start preform, every item in the screen is duplicated and mirrored upside down. While working on importing stl’s and generating support it will almost Always flicker between normal and upside down mirrored and only sometimes both.
Using 8.1 64X with an old onboard intel hd graphix card on my laptop with the latest drivers and updates.
You may want to check all the video drivers. My laptop recently decided to eat the windows drive. After rebuilding I updated the video card drivers as I did when I first installed 1.90 and it bombed. Turns out on my machine there is an intel graphics driver and a driver for the actual video card.
Once I had both up to date everything started working.
The software does appear to be graphics intensive so an older video card might not be all that happy. Maybe a feature request would be a low resolution version of the software.
Unfortunately I already have the latest drivers, no troubles untill this release. appart from slowness i have no issues with meshlab, netfabb openscad and other 3d applications (except for slowness). While i think drivers have at least some part in the issues preform makes it worse. I too would like an option to run in lower quality graphix (I like stunning prints better than stunning graphix )
