Description Paulo Dias 2015-01-28 11:59:40 UTC

kscreen doesnt resize the screen correctly.

If i resize the screen to, lets say, 1280x1024, kscreen does resize it correctly, BUT when going back to the original size (1920x1080), it resizes only to 1/4 lower left size, and the rest of the screen remains garbled. if i then force the resize with xrandr -s 1920x1080 it works fine.

Reproducible: Always

Steps to Reproduce:
1. open kscreen
2. resize to a smaller sizer
3. resize back to the original size

Actual Results:  
the screen is cut by 1/4 and rest remains garbled

Expected Results:  
the screen should be resized correctly
