Expected behavior

Text editing using terminal URXVT should work fine

Current Behavior

Portions of text simply disappears while scrolling, and if I enable cursor blinking in urxvt portions of text start blinking as well. This weird behavior stops when I kill compton.

Another example is I open vim, edit something and close it, the bottom part of my text file appears on my terminal even after I close vim.

Further debugging shows other weird behavior when compton is running.

  1. When i am editing text in vim, say I am in line 221, if I press the down arrow key, part of the text goes blank but the line indicator says i am in line 2, now if press the down arrow key again I am in line 223 and the text reappears, this keeps happening almost every other line.

This issue disappears when I kill compton and seems to happen only on urxvt, so possibly it could be a problem with urxvt doing something wrong when compton is running.

vikigenius commented 5 years ago

After a few more hours of searching I found https://github.com/chjj/compton/issues/152. Using the --xrender-sync-fence switch as suggested has solved the issue.

yshui commented 5 years ago

@vikigenius Mmm, this should be automatic for NVIDIA drivers.

Can you post the output of compton --diagnostics?

vikigenius commented 5 years ago

Sure thing @yshui 

**Version:** v7

### Extensions:

* Shape: Yes
* XRandR: Yes

### Misc:

* Use Overlay: Yes
* Config file used: /home/void/.config/compton.conf

### Drivers (inaccurate):

NVIDIA, 
yshui commented 5 years ago

@vikigenius The driver is properly detected, so --xrender-sync-fence is automatically enabled.

Are you sure passing that flag does solve the problem?

vikigenius commented 5 years ago

I am sure, it is now completely resolved after passing the flag, no more weirdness, it was not very subtle so it is easy to notice.
