Dear Dyari,
I can't take a photo, given that it's a half-second flash. I know I probably shouldn't mention it here, but for testing purposes I installed a Libre Office program, where the same document, on the same line, doesn't make this error. What else I observed: the document is 2 pages, but the error is not visible in the upper three-quarters. But, if we go down in the document, write a new line, or delete a line and press enter, the old line above the new line flashes for a moment. Device parameters:
