System Information
Operating system: Linux-5.3.0-42-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 1660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 435.21

Blender Version
Broken: version: 2.83 (sub 10), branch: master, commit date: 2020-03-19 21:12, hash: d2c3544c5c
Worked: unknown

Short description of error
The title says it all: When I add a Gaussian Burr, any new selection will immediately trigger the problem.. Be careful when testing: Within seconds, Blender consumes all my memory (16GB) and locks up the computer. Not even the mouse moves any more, I need to reboot.

Exact steps for others to reproduce the error

Start a new project in VSE mode
Add any strip - even a color strip will do
Add the effect strip "Gaussian Blur"
Select the color strip (from 2.) and add strip modifier "Mask"
Set "Mask Input Type" to "Strip" and set Maks to "Gaussian Blur"
So far so good. Now, if I move cursor to a different position in the strip, Blender locks up within seconds. I have a memory widget on my toolbar, where I can see how within 2-3 seconds, all memory is consumed. At this point, the mouse locks up. I can't even switch to the console any more. I have to restart the computer using the power button.
