User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:98.0) Gecko/20100101 Firefox/98.0
Steps to reproduce:
searched for the same problem (difficult keywords to filter out unwanted stuff), restarted Thunderbird, rebooted computer, upgraded to latest Linux kernel, perused Thunderbird settings for anything new that could be relevant.
Actual results:
Beginning with the 91.5.0 update, any time I open an email, the background message pane shows through it. I have to toggle between window views (either Thunderbird, something else open like Firefox, or multiple emails if more than one is opened), or scroll down if the email is 2+ pages, to get it to appear.
This is on Linux Mint 19.3 Tricia 64-bit. There is no shortage of memory or CPU% available.
Expected results:
Prior to the 91.5.0 update, the emails always opened with no such problems. I'm now on 91.7.0 and the problem persists.
Try changing the hardware acceleration in preferences.
That sounds like video driver compatibility issue. You might also want to check if there is a proprietary driver for your hardware available from the vendor if the repo supplied one is open source. They tend to not exhibit the same number of issues.
Thanks for the reply. Hardware Acceleration (when available) was enabled. I disabled it and that seems to have fixed it!
The video driver didn't change, FWIW, nor did any other hardware. It had to be something within Thunderbird, beginning with the 91.5.0 update. Glad it was something as simple as a setting. Unless you meant that hardware acceleration is offloading the task to a video driver that is no longer compatible with Thunderbird's needs?
I really don't know what hardware acceleration does or how it benefits Thunderbird. We had it turned off by default for years because it is home of these odd graphics issues. As video is not a large part of Thunderbird's mail functions I think it should still be turned off by default. But the developers are determined we must have it.
Something about Firefox turn it on so we must as well because they test with it turned on.
Yeah, I looked it up after your first reply and saw no good reason to keep it enabled, so it's a no-brainer to uncheck it if it's causing problems like it did for me.

Does this happen for you withversion 115?
I'm on 115.6.0 currently, and it hasn't occurred for me since the Hardware Acceleration fix two years ago.

I guess what I should have asked is, do you see the problem with acceleration enabled?
I re-enabled hardware acceleration, and I'm not seeing the problem after restarting Thunderbird. So, it does appear to have been fixed at some point.
Resolved per whiteboard and Comment 8
