Visible motion blur without "\cairo-dock-motion-blur-plug-in" string in text editor

Description of problem:
Cairo-dock-motion-blur-plug-in plugin is creating fake motion blur
and input delay lag everywhere.
I haven't installed it but this is apparently so.

If you write in text editor
"\cairo-dock-motion-blur-plug-in"
cairo motion blur plugin is apparently shut down
somehow, maybe because of backslash character "\"
which is used in regexp.



Steps to Reproduce:
1. Cairo-dock-motion-blur-plug-in plugin is creating fake motion blur
and input delay lag everywhere.
2.
3.

Unfortunately I don't understand what you want to say here.
Especially, if you have not installed cairo-dock-motion-blur-plug-in, it is obvious that the issue you are seeing (although currently I cannot understand what it actually is) is not due to cairo-dock.

Everything looks like its under heavy, but fake motion blur.
If you write, for example in text editor "\cairo-dock-motion-blur-plug-in"
everything is immediately much faster and fake motion blur is gone.

Even better approach apparently is to replace for example
browser url the following way thus skipping lengthy "\cairo-dock-motion-blur-plug-in" string:


\ + url



For example:

\ + https://bugzilla.redhat.com  >  \https://bugzilla.redhat.com
\ + https://www.google.com  >  \https://www.google.com




This suggest either someone made regexp mistake or compiled
fake motion blur somewhere and it is activated constantly.

If url is blank, e.g. new tab page you can write:
"\blank".

\"\blank\"


Has less input lag.
:)

Comment 6 mouseyklfyt 2021-02-21 14:16:02 UTC
Two scenarios:

blank url   >   \"\blank\"
url   >   \ + url



This fixes input lag and removes
undesired fake motion blur effect.
:)

Comment 7 mouseyklfyt 2021-02-21 15:40:14 UTC
Actually you can replace any url with
\"\blank\"  

This appears to be best possible scenario?
What it is when? Fake motion blur + gamma and brightness drop?
Why?
Because of mistake in cairo-dock-motion-blur-plug-in?
:)

> \"\blank\"



- improved scrolling
- improved brightness
- fake motion blur is gone (possible cause could be "cairo-dock-plug-ins")
- faster text 
- faster keyboard (less input lag)

\"\nouveau\"\_

is even faster!
