Screenshot of the Blender window glitching

I should add another detail to the discussion. I know this may be a separate
issue which might have nothing to do with the crash, but at the same time I
wouldn't be surprised if it does: Glitched graphics often indicate something
going wrong with the display, such as corrupt textures in video memory, which
may ultimately lead to just such a lockup.

On occasion, certain programs (namely Firefox and Blender) glitch out and draw
broken rectangles all over the window. Some of those glitches are just boxes of
random colors, others contain pieces of past images (for instance I saw
patterns from my lock screen background). Sometimes they quickly disappear on
their own, at other times I have to restart the program as it becomes illegible
and unusable. If I move anything the squares flicker all over the place. The
glitches continue even after I disable desktop effects, thus KDE compositing
should have nothing to do with it.

Attached is a screenshot of the glitch happening in Blender, showing its window
covered in the corrupt squares. I'm curious what your opinion is. Again I know
this may be an unrelated issue, but I'm wondering whether it indicates some
video storage corruption that's also leading up to the lockups.
