Bug ID: 505133
Summary: Resizing electron-based window in KDE Plasma from left
or top often makes the window unresponsive for 8-10
seconds
Classification: I don't know

OS: Linux
Status: REPORTED
Severity: normal

Screen recording showing the issue
SUMMARY
When I resize an Electron-based application's window (e.g. Discord, Obsidian or
VSCodium) from the top, left or top-left corner, the application often becomes
unresponsive for ~9 seconds. Resizing from the bottom, right or bottom-right
corner does not trigger the freeze. During the freeze, I cannot resize or click
within the application, but I can still move the window.
The more time spent resizing, the higher the likelihood of the
freeze/unresponsiveness triggering. The distance resized does not seem to
matter, it's more about the time spent resizing.
Sometimes it freezes nearly every time I resize; other times, it only happens
every 10th to 20th attempt. When exactly it will happen seems inconsistent and
nondeterministic to me. Most commonly, it happens every 2-4 times that I resize
an electron window from the top or left side.
STEPS TO REPRODUCE
1. Open an Electron based app (e.g., Discord or Obsidian)
2. Resize the window from the top, left, or top-left corner, for a few seconds.
3. The application will be unresponsive for ~9 seconds.
OBSERVED RESULT
The window becomes unresponsive (frozen) for 8-10 seconds.
EXPECTED RESULT
The window should resize without freezing or becoming unresponsive.

I have a 144Hz monitor - it also happens when changed to 60Hz.
I tried launching Obsidian with --disable-gpu, this did not make a difference.
I tried running Obsidian with `WAYLAND_DEBUG=1`, however no messages show up in
stdout or in journalctl when the freeze/unresponsiveness happens.
