huge delays when pressing keys with image background on multiple monitors

[mdeff]

With an image background displayed on multiple monitors (laptop monitor and 2 external screens), I experience huge delays (i.e., delays from key presses to visual acknowledgments). Also, the three displays are not synchronized (key presses are shown at different times) and CPU usage is very high while I enter my password.

It's smooth without a background image. There's a small delay with one monitor (laptop screen), but it's much better.

Is that a known issue? Could that be due to the image format? (Mine is a 4000 x 2330 PNG.)

swaylock should be able to handle huge images correctly.

Which version of swaylock are you running? Please try the latest commit. There are unreleased changes that improve performance.

I was using version 1.3. The problem is indeed fixed in master. Looking forward to the next release!
