On sway (wayland), warpd sometimes hangs in `discover_pointer_location` #293

Open dylanfprice opened 2 months ago

dylanfprice commented 2 months ago

Issue

After using warpd for a while, any attempt to start warpd will cause warpd to hang in I believe the discover_pointer_location function.

Observed behavior is that I start warpd and the mouse moves a tiny bit, but no red dot is drawn and the keyboard is not captured by warpd. Wish I could share a video but my screen capture is also having issues right now :)

It seems to me that this behavior usually starts after doing some dragging operations in a previous warpd process, but that is a complete hunch and not verified.

Setup

$ warpd -v
warpd v1.3.5 (built from: 01650ea)

$ sway -v
sway version 1.9

I have no warpd config. I have one monitor plugged into my laptop (lid closed and laptop monitor disabled via sway).
