mcpop909 Posted January 6 Share Posted January 6 (edited) I've just reinstalled Windows 10 on my PC and have v. 5.0.12 of Paint.net freshly installed on it. I have now re-encountered a problem I have had before with weird flashing and glitching when trying to use the wand magic. It looks like a hardware problem, except that it's only affecting the paint.net image, not the whole screen, which seems evidence against that. I have attached the diagnostics report below and an image showing this and have uploaded a video showing the flashing to https://www.dropbox.com/scl/fi/t69uowhkwxynbki1sv2wa/Paint.net-glitch.mp4?rlkey=ngbxjsopd03anva1816auxyvx&dl=0. I am also running Wondershare Filmora v 12 and ScreenPal. As I say, I had this problem before and either I solved it or it solved itself, but I have no idea how, so any help is much appreciated.

Tactilis Posted January 7 Share Posted January 7 Welcome to the forum @mcpop909 Have you checked that your graphics drivers are up to date after the reinstall? Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted January 7 Share Posted January 7 Yeah this definitely looks like a GPU issue. Since this is a fresh install of Windows 10, it's very important that you get all of the updates that are available for your system. Open up Windows Update and install everything it has available. Keep repeating this (with reboots when it says to) until there's nothing else. Make sure you have the latest GPU driver from NVIDIA installed. It looks like you have version 388.73 which is very old. You have hardware acceleration disabled for the UI/canvas for some reason -- you should enable that.

Rick Brewster Posted January 7 Share Posted January 7 You should also try disabling "Wondershare Filmora" and "ScreenPal".

Solution mcpop909 Posted January 7 Author Solution Share Posted January 7 Thanks, Rick and Tactilis, I tried updating the NVIDIA driver both using the Lenovo Support Bridge, which failed, and then from softpedia.com, which also failed to install. Windows Update reports that everything including optional things is up-to-date. Solved the paint.net problem by going to Paint.net's settings > Graphics > Rendering device and changing that to Intel HD Graphics 530 instead of NVIDIA GeForce 930A. Also re-enabled Use hardware acceleration. Now working OK. Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted January 7 Share Posted January 7 You can update the NVIDIA driver by going to NVIDIA's website and clicking "Drivers" at the top. The GeForce 930A should have significantly better (faster) performance than the Intel HD 530, so it's probably worth trying to get that working.

mcpop909 Posted January 19 Author Share Posted January 19 None of that worked. I got onto Nvidia's live chat and followed their instructions, which, after everything failed, led to a reinstallation of Windows and updating the Nvidia graphics card. Still exactly the same.

Rick Brewster Posted January 19 Share Posted January 19 Then it’s a bad GPU. Replace it — could use a friend’s temporarily to see if that helps Quote The Paint.NET Blog: https://blog.getpaint.net/ Donations are always appreciated! https://www.getpaint.net/donate.html Link to comment Share on other sites More sharing options...
BDP Posted January 20 Share Posted January 20 Have you tried NVCleanstall from https://www.techpowerup.com/download/techpowerup-nvcleanstall/ Works great, and picks the correct driver for your GPU Brian Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted January 20 Share Posted January 20 @BDP, probably won't help -- they already did a clean install of the entire OS. And if you need the latest drivers for a GeForce (930A in this case) just go to nvidia.com, no need for some random utility program. It really does look like a failing/failed GPU. The vertices for the selection data are obviously mangled, and nothing short of blatant memory corruption somewhere along the way could cause that.

BDP Posted January 21 Share Posted January 21 Rick, You know better than myself with these things, but I have had a few failures with the NVidia site, in that it identified my GPU but failed to install correctly when downloading their selected driver. Never had any bother with the NVCleanstall application Brian Quote Link to comment Share on other sites More sharing options...
