This is my first bug report here, so I hope i got everything right.

My system is Fedora 22. My GPU is a Sapphire 280x OC. My secondary screen, connected via dvi, is showing strange vertical stripes, ca 3 cm wide. It seems like someone cut the actual image in stripes and glued it together slightly overlapping with flickering borders.

If I take a screenshot everything looks normal (as it actually should look).

If I use it as the only screen, the stripes are also there. (Is it a problem with the screen or the dvi connection?) I tried the second dvi connection with the same result.

Using Windows, the screen has no issues.

As mentioned, screenshots show the image as it should be, I had to take a photo of the screen. I used a text file with the repeated series if numbers from 1 to 7.So one can see where the overlapping I mentioned happens (also in the spacing of the buttons, missing glyphs etc..) for example, after the first 1-7 sequence, the 1 and 2 are left out and so on. I am sorry but I found no better way to show it, except making a video

If you need more information please let me know.
