Description

System Information
Operating system: Linux-5.15.28-1-lts-x86_64-with-glibc2.35 64 Bits
Graphics card: NVIDIA GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.54

Blender Version
Broken: version: 3.1.0, branch: makepkg (modified), commit date: 2022-03-08 18:16, hash: rBc77597cd0e15
Worked: 3.0.1, branch: master, commit date: 2022-01-25 17:19, hash: rBdc2d18018171

Short description of error
Grease Pencil function to fill inverted area freezes Blender and then whole system.

Exact steps for others to reproduce the error

  • Launch Blender
  • Open a new 2D animation file
  • Draw a box inside another box
  • Select fill tool
  • Select a fill material
  • Change the fill direction to 'inverted' by selecting '-' button

  • Click anywhere inside the inner box or outer box
  • Nothing happens other than a few pixels wide small black square with numbers '5 0' appearing. It immediately freezes Blender. In a few seconds or immediately mouse or keyboard stops working. I have to restart computer using power button. On one occasion I was able to open system monitor to see CPU was working at 100%. On that occasion Blender crashed rather then system freeze.

Confirmed. Might be a memory leak, since the RAM usage is getting higher and higher when doing that and Blender crashes.

If you are on KDE you can save your computer from going down by pressing Ctrl+Alt+Esc and then click on blender to kill it.

Thanks. I am on Cinnamon. Just refreshed my memory of xkill process if keyboard is still active: Alt+F2 to launch dialog box > xkill > click on Blender to kill it.

It kills Blender. Then in about 5-10 seconds mouse and keyboard freezes. Memory and CPU overloads according to system monitor. It lasts about 20-30 seconds until they are released again.

It looks an infinite loop more than a memory leak
