P: gpu issues

Does it make a difference if you try doing a clean driver install of the latest game driver? Follow Solution 4 of this troubleshooting guide https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html to do a clean driver install.

When I tried to work on very large images, the problems were worse. For example, I have a pano that is something like 26,000 x 6,000 pixels and it was impossible to do any DM changes.

Can you help elaborate on this on the issues that you ran into when you did it?
