Selection tools cause entire canvas to melt and become black
GIMP version: 2.10.8 Operating System: Windows 10. As for the updates version, it is November 25 2018 and there's no available updates pending.
Package: [flatpak? Installer from gimp.org? If another installer, tell us where from]
Description of the bug
Any time I make a selection of any sort with either the box select, lasso, or circular select, the entire canvas goes crazy. It is not easy to explain. Basically, ever pixel on the canvas begins to get darker, and move to the lower left, and eventually my whole canvas turns black. It's very bizarre and basically makes using any selection tool unusable. In order to get things back to normal, I can either reload the document, or go to Select->None, then move another tool such as the paintbrush or the pencil around the canvas. As the cursor moves around the canvas, it "clears up" the canvas areas that it touches, returning it to it's normal look.
Please describe your issue with details. Add screenshot or other files if needed.
Is the bug reproducible? [Always / Randomly / Happened only once ] EVERY TIME. NO EXCEPTIONS.
One thing that might be different in my case, which is an exception from other users, is my computer is a Wacom Mobile Studio Pro 16". Probably not a heck of a lot of people with this particular computer using GIMP. Maybe if it's hardware related, it could explain why this bug hasn't been reported by anyone else yet.
- Select any selection tool.
- Make a selection on the canvas.
- Watch the chaos unfold.
Expected result: I should have a selected group of pixels that I can move around inside of the canvas.
Actual result: My entire canvas melts like butter in an oven.
