Hey there, sorry to hear you're stuck with this annoying window positioning glitch after waking your system from suspend! This seems like a common state-sync bug with GNOME's Mutter window manager in older versions like 42.9. Let's go through some practical fixes that other users have had luck with:

Reset Mutter window manager settings
Sometimes cached window state data gets corrupted after suspend. To fix this, open a terminal and run:
dconf reset -f /org/gnome/mutter/
Then log out and back in. This will reset window management-related configurations without messing up your other GNOME preferences.
Check for conflicting GNOME extensions
Third-party extensions (especially those that modify the sidebar or window behavior) often clash with system window positioning. Open the GNOME Extensions app, disable all extensions temporarily, then restart your system. If the problem goes away, re-enable extensions one by one to find the culprit—you can either update that extension or disable it until a fix is released.
Toggle window snapping settings
Head to GNOME Settings → Multitasking, then find the "Window snapping" options. Try turning it off, applying the change, then turning it back on. This can reset the window positioning logic that might be misbehaving after wake-up.
Automate window refresh with a script
If the above fixes don't stick, you can create a simple script to auto-refresh window states after suspend. Here's how:
1. Create a file named fix-window-position.sh with this content:
```
#!/bin/bash
# Refresh all windows by toggling minimize/maximize
wmctrl -l | awk '{print $1}' | while read win_id; do
    wmctrl -i -r "$win_id" -b toggle,hidden
    wmctrl -i -r "$win_id" -b toggle,hidden
done
```
1. Make it executable with:
  chmod +x fix-window-position.sh
2. Set it to run automatically when your system wakes up—you can use GNOME's "Startup Applications" tool or set up a systemd service for this. It's a workaround, but it saves you from manually minimizing/maximizing windows every time.

Also, keep an eye on system updates—run sudo apt update && sudo apt upgrade regularly. GNOME often patches these kinds of window manager bugs in minor updates, so a future update might resolve the issue permanently.
