I'm at a loss actually, I tried to copy the rendering method from rpi4-osdev bypassing the stuff in the `fb` example and the spots are still there. Not sure what's causing them. I don't think it's the overscan because if the over-scan pixels were in the framebuffer, the size would be much larger. I think the framebuffer has extra length due to memory alignment in the allocation process. If I shift the stride, or reduce/increase the resolution by 1, I get warped results as I would expect. The framebuffer example is all rendering fine besides the lines, which makes me wonder if it's something to do with timings between frame-buffer changes and HDMI video output/sync? Needs more experimenting. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
