Wrong Window Moved When Dragging with Mouse

Welcome

We appreciate you taking the time to report this issue. This article will guide you through the steps to reproduce the problem and provide a detailed description of the issue.

Current Behavior

When starting the drag of any window with the mouse, there's a chance that a different window will get its position erroneously changed. Sometimes, the window goes back to its original position after dragging is finished. This is not a visual bug, the position does actually change. This only seems to affect a single window, regardless of whether it's tiled or floating; if that window is closed, the bug seems to stop occurring until new windows are open. If the dragged window is the one affected by the bug, it jerks for a frame when dragging begins. This occurs regardless of whether the window is dragged by the title bar or by holding floating_modifier. If the window is on a different monitor, it changes the workspace it's on without changing its position. This bug does not seem to occur when the window is hidden on a different workspace, so a workaround is to create a sacrificial window and move it to an unused workspace.

Expected Behavior

This does not occur.

Reproduction Instructions

To reproduce this issue, follow these steps:

Create some windows.
Rapidly drag them until one starts to glitch out.

# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below.
font xft:Roboto Mono 8

# This font is widely installed, provides lots of unicode glyphs, right-to-left
# text rendering and scalability on retina/hidpi displays (thanks to pango).
#font pango:DejaVu Sans Mono 8

# Before i3 v4.8, we used to recommend this one as the default:
# font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, its unicode glyph coverage is limited, the old
# X core fonts rendering does not support right-to-left and this being a bitmap
# font, it doesn’t scale on retina/hidpi displays.

**Wrong Window Moved When Dragging with Mouse: Q&A**

**Q: What is the issue with the window movement in i3?**

A: The issue is that when starting the drag of any window with the mouse, there's a chance that a different window will get its position erroneously changed. This can cause the window to move to a different location on the screen, even if it's not being dragged.

**Q: Is this a visual bug or a real issue?**

A: This is a real issue, not a visual bug. The position of the window does actually change, and it can cause problems with the layout of the workspace.

**Q: What triggers this issue?**

A: This issue seems to be triggered by rapidly dragging windows. If you drag a window quickly and repeatedly, there's a chance that a different window will get its position changed.

**Q: Is this issue specific to a certain type of window?**

A: No, this issue seems to affect all types of windows, regardless of whether they're tiled or floating.

**Q: Can I prevent this issue from happening?**

A: Unfortunately, there's no known way to prevent this issue from happening. However, you can try creating a sacrificial window and moving it to an unused workspace. This can help to prevent the issue from occurring.

**Q: Is this issue specific to a certain version of i3?**

A: This issue seems to be present in version 4.24 of i3. However, it's possible that it may be present in other versions as well.

**Q: Can I report this issue to the i3 developers?**

A: Yes, you can report this issue to the i3 developers by creating a new issue on the i3 GitHub page. Be sure to include as much detail as possible, including the steps to reproduce the issue and any relevant configuration files.

**Q: Is there a workaround for this issue?**

A: Yes, one possible workaround is to create a sacrificial window and move it to an unused workspace. This can help to prevent the issue from occurring.

**Q: Can I use a different window manager to avoid this issue?**

A: Yes, if you're experiencing this issue with i3, you may want to consider using a different window manager. Some popular alternatives include XMonad and Awesome WM.

**Q: Is this issue specific to a certain Linux distribution?**

A: This issue seems to be present on Arch Linux, but it's possible that it may be present on other Linux distributions as well.

**Q: Can I use a compositor to fix this issue?**

A: Yes, you can try using a compositor like picom to see if it helps to fix the issue. However, this may not be a reliable solution.

**Q: Is there a way to debug this issue?**

A: Yes, you can try debugging this issue by running i3 with the `--debug` flag. This can help to provide more information about what's causing the issue.

**Q: Can I use a different configuration file to fix this issue?**

A: Yes, you can try using a different configuration file to see if it helps to fix the issue. However, this may not be a reliable solution.

**Q: Is this issue specific to a certain hardware configuration?**

A: This issue seems to be present on a variety of hardware configurations, but it's possible that it may be more common on certain types of hardware.

**Q: Can I use a script to automate the process of fixing this issue?**

A: Yes, you can try using a script to automate the process of fixing this issue. However, this may not be a reliable solution.

**Q: Is there a way to prevent this issue from happening in the future?**

A: Unfortunately, there's no known way to prevent this issue from happening in the future. However, you can try keeping your i3 configuration up to date and using a recent version of i3.
