Every window that I try to resize responds incredibly slowly. The windows in Chrome and Firefox are especially slow to resize and refresh. I even experience this delay in the terminal. I am absolutely dependent on instantaneous refreshes as I am working with responsive websites.

I run a GTX 1080 and a 1440p 144Hz monitor. Live resizing on Windows works flawlessy.

These are the things that I've tried so far, but that didn't help fixing my issue:

I uninstalled all of my existing NVIDIA drivers. I downloaded the proprietary 375.26 drivers for my 1080 from the NVIDIA download page. I continued to install this .run file via the terminal. Before that I tried the open-source 375.26 ones, but those didn't work either.

I changed my display rate to from 60Hz to 144Hz.

I installed the Compiz Configs Settings Manager. I made sure that the default resize mode is Normal (which basically means live window refresh on resize).

  • Can you show lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA? Just to make sure you're really using your gpu? – Dark Sinus Feb 13 '17 at 15:47
  • Yes the 1080 is the active GPU since it's the only graphics card that is installed on my system. I don't have integrated graphics as well. – Thomas Hartmann Feb 13 '17 at 15:57
  • Ok and can you see how much it is used when you resize a window? Like with watch nvidia-smi on a term and you resize a browser window to see if there is sth wrong with the GPU usage? – Dark Sinus Feb 13 '17 at 16:05
  • GPU utilization spikes up to 20-30% when I resize a window in Chrome. – Thomas Hartmann Feb 13 '17 at 16:16
  • I am tempted to reinstall Ubuntu – Thomas Hartmann Feb 13 '17 at 20:03
