Every time I leave QCAD open for a few minutes, and my computer enters power-saving mode (turning off the monitor), QCAD becomes unresponsive upon returning. The only way to recover is to kill the process and restart QCAD forcefully.

Steps to reproduce:

  1. Open QCAD.
  2. Leave it idle for a few minutes until the system enters power-saving mode (the monitor turns off).
  3. Wake up the system and try to interact with QCAD.

Expected result:
QCAD should remain responsive after the system wakes up.

Actual result:
QCAD becomes wholly unresponsive and must be forcefully closed and restarted.

System information:

  • QCAD version: 3.32.2 (and many older versions)
  • Operating system: Ubuntu 24.04

Additional notes:

  • The issue occurs consistently.
  • No error messages are displayed.
  • Other applications remain responsive after waking up the system.

Unfortunately it’s very unlikely that we can fix this as it seems to be a problem between Qt and your particular setup. QCAD does not do anything when a system goes to power safe mode or wakes up, this is all handled on a much lower level.

Please contact us for a refund.

In steps to reproduce:
'Leave it idle for a few minutes'

Perhaps already a solution to turn idle after a longer period.
Like 1/2 hour.
