Window flickering with monocle mode and FOLLOW_MOUSE

[YellowKirby]

Hi, I've noticed that in some cases, changing focus in monocle mode while FOLLOW_MOUSE is true will cause a rapid, fullscreen flicker, as if the focused window is very rapidly changing. I'm not exactly sure what triggers it, but one way I've been able to reproduce the issue is to do the following:

(this is using the master branch; FOLLOW_MOUSE is True; the rest of config.h is the default):

• Start with an empty desktop in the default tiling mode
• Spawn two windows, side by side. (The problem will be much more apparent if the windows have different backgrounds; a dark and a light)
• Switch to Monocle mode
• Spawn a third window
• Change focus with Mod1+j

At this point, the flickering occurs, and remains that way until switching back to a different tiling mode.

The issue does not happen when FOLLOW_MOUSE is False.

Thanks!

hi,

this is known but I've yet to find a clean solution. i do have one thing in mind, but my psu is dead and until I replace it,i have nowhere to try the code on.

hopefully it's fixed for good.
please build and test with the new code.
if it doesn't work reopen and report back ;)

Hi, developer

I found this issue still exists for the present git version.

But the flickering only happens when using "Mod1+j". "Mod1+k" is always fine.

So i only use the later one now.
