Reader suddenly broken

[VMedic77]

Hi
I was using Sumatra for a while and it was small,fast and clean solution. After switching from win 7 to win 10, after a while,my reader doesnt show top 1/7-th of a screen (approx)...it is just blank white or black. When I press shortcuts, it all works, but I just cant see it. I tried 3.3.3 and pre-realese 3.4, same thing. I have no clue what is going on,but noticed that when I click on that blank area, whichever desktop icon that is on that position where I click (that I cant see) activates,like that part of a screen is messed up completely and out of the application. Any thoughts ?

never seen anything like that on various machines so try to get a screenshot of differing views perhaps with sidebar

if the portable version https://www.sumatrapdfreader.org/dl/prerel/14472/SumatraPDF-prerel.exe works its perhaps a settings issue but if portable does not function it is perhaps a graphics driver problem

Thank u for reply.
Now that u mentioned it, I investigated further and realized it is indeed graphic driver problem. I have multiple monitors and SCALE FULL SCREEN on secondary monitor must be checked and override app settings must be checked to fix this issue. (IntelHD graphics)

there are many ways to change an apps graphics but perhaps check if you need to alter some of those properties in driver or application
