Lightroom Classic 8.0: Problem with blank main image display window in Develop module

I would like some help with a bug that I have had since therelease of 8.0.

Whenever I have a photo open in the library module, and Iclick on the develop module tab, I go to the develop module, and everythingappears to be OK, except that the main image display window is black.  The preview window in the upper left corneris OK, and the histogram is fine.  I canmake any change to the exposure settings and see the histogram and preview windowschange accordingly.  I can go back to thelibrary module and the main image windows displays the selected photo, but onreturning to the develop module, the main image window is black.

I would say that this occurs on 19 out of 20 times that Iswap between the library tab and the develop tab.  On the 20th time, the develop tab opens justfine with the selected photo on display in the main image display window.

The only way to get out of this is to close LR while in developmode, and open LR up so that it opens in develop mode.  After it starts, I can see the main imagedisplay just fine.  I can work for hourswith no problem.  But, if I go to the librarytab, and then swap back to the develop tab, the main image display is againblack, and I have to restart LR to get the main image display widow to show theselected photo.

This has been going on a while.  I have wiped my hard drive once and reloadedeverything, and I have replaced the hard drive once, and reloaded everything.

I have updated my display drivers, and upgraded the bios onmy system.  I have tried two different monitors.

I’m using a Dell XPS Core i7 that is older, but stillsufficient for my needs.  I use Windows10 Pro.  I have used LR on this PC foryears with no problem until LR 8.0

I’m at the point of downloading trials for Luminar, ACDSEE,and Capture 1, but I just don’t want to try to learn a new interface (I’m goingto give Luminar another shot when they release their DAM module.)



Any help would be appreciated.
