Mouse cursor disappearing at top of screen

After last update (maybe the nvidia drivers?) my mouse disappears at the top of the screen, an workaround is to set underscan in nvidia-settings to 1 so my screen resolution is 1918x1078 instant native 1920x1080.

Using awesome wm, Benq GW2450H via HDMI.

Re: Mouse cursor disappearing at top of screen

Also have this problem (nvidia, but openbox with a DVI-D monitor). Setting underscan to 1 and then reverting back to native resolution seems to fix it.

EDIT: only until X restart. Upon further investigation, it seems to be related to the ForceFullCompositionPipeline=On setting that I need to remove screen tearing. Disabling the setting in xorg.cong solves the cursor issue, but reintroduces tearing, which is worse.

Is this set by default? I didn't set it but I have set it in 25-screen.conf. Did you try maybe beta drivers if it is fixed?

EDIT

You can disable FFCP at runtime with:

nvidia-settings -a CurrentMetaMode="DFP-0: 1920x1200+0+0, DFP-1: 1920x1080+1920+0 { ForceFullCompositionPipeline = Off }"

But when you try to re enable it the problem is back, sot it is really the ForceFullCompositionPipeline.

EDIT

This fixes it without disabling FFCP:

nvidia-settings -a CurrentMetaMode="DFP-1: 1920x1080 +0+0 { PanningTrackingArea = 1920x1080 +0+0 }"

But I am not sure how to add it to X11 conf.d or if it will work, now I am adding this to autostart.

I don't think FFCP is enabled by default. However, if you don't experience/care about screen tearing (it is only an issue with some recent GPU models, as far as I know), you can safely disable it.

Well I have gtx 770 , I think I can call it "recent". The command with I post above works fine too, only small screen flicker when it launches but much better then running underscan with complete reload awesome since the resolution changes.
