From 5bd6a5ce3ff3cb879463646d4f88745420335b23 Mon Sep 17 00:00:00 2001 From: Tudor Brindus Date: Sun, 18 Oct 2020 15:55:52 -0400 Subject: [PATCH] transaction: don't reconfigure X views unless integral coords changed Sway logical coordinates are doubles, but they get truncated to integers when sent to Xwayland through `xcb_configure_window`. X11 apps will not respond to duplicate configure requests (from their truncated point of view) and cause transactions to time out.
