Description Soukyuu 2015-05-29 14:14:45 UTC

I don't even know what it does, exactly. The whole desktop becomes scrollable, so that I have a black bar with nothing on it below my monitors (see attachment). It also destroys widget sizes/position. Changing resolutions on both of the monitors does not fix the issue.

Reproducible: Always

Steps to Reproduce:
1. change from 1920x1080+1280x1024 to 1920x1080+1920x1080
2. change from 1920x1080+1920x1080 to 1920x1080+1280x1024
3. move the mouse to each edge of each screen

Actual Results:  
Desktop scrolled past the define resolution, showing black bars

Expected Results:  
Desktop should have been constrained to the monitor resolution

This might or might not be because my second monitor has a vertical offset of 60 defined, so that it doesn't start at (1920,0) but (1920,60). It seems that switching to 2x 1920x1080 keeps that offset, and changing back keeps the virtual space for monitor 2 at 1920x1080, even though the resolution is now 1280x1024.

Logging in and out helps, but that is just annoying.

Note that the panel on the right now has a weird offset and the rightmost section with the dolphin window is actually old screen content that doesn't get updated anymore.

Not sure if it's relevant, but I'm on nvidia 340xx legacy drivers, 260GTX GPU

I have the same problem. I'm also having a Nvidia card, driver version is 346.59. But I'm using Kubuntu 15.04 with Backports PPa activated.

I have confirmed this is kscreen causing it. Stopped using it and switched to just setting modes with xrandr and switching between two layouts works without the weird side-effects.
