That almost sounds like a GPU overheating problem... check internal temperatures if you have a way to. Don't mess with dynamic RAM preview settings, it is mis-named, it doesn't affect preview at all. Only shift+B dynamic RAM preview.

Well the Ram preview is always at 50 percent and has never done this before. I have been using Vegas for nearly 10 years and this has never happened. There are 3 GPU Temps and the highest 1 is always 68 degrees or less. This has never happened before and I have been using Vegas for nearly 10 years with not that many problems. Sometime I would need to change internal settings and things would be fine but nothing is working to stop this. I just edited for about an hour and a half and then it glitched/corrupted which you can see in the image. Menu is messed up and you can see a bit of the glitching in the bottom right hand corner at the end of the white audio line the bar has gone black and they flicker and have corrupted vertical lines on them when I move the mouse.

you never want to hog up half of your ram for a feature that you probably don't use that often, if at all. dynamic RAM preview isn't how much RAM it uses to preview, it's how much RAM VEGAS renders frames to when you use the shift+B dynamic RAM preview option, that's it... so you're hogging up half your RAM for something that is only used when you press shift+B to preview a section of your timeline, making VEGAS run worse along the way. Yet another reason why I believe dynamic RAM preview needs to be removed or renamed...

as for the rest... it's an unusual issue, one I've only seen happen on defective cards or bad drivers... and you say you've updated the driver, so I'm not sure. If it only happens in VEGAS, and your temps are ok, that's a good sign that it isn't hardware related...

There are no issues in anything other programs I use or games I play. Even playing Graphics intensive games, while streaming to YouTube, my GPU never gets over 70/75 temp and my CPU is around the same temp in games. I will turn the ram preview down then. I do know what it does but I like to preview larger sections of my videos as I edit if I want to see a full slow down effect into another edited section and sometimes it wouldn't have enough to preview the whole piece in one go. I don't think that would not cause the visual issue I seem to be having. I'm stumped really. I can save and restart and edit again straight away for just as long with no issue and then It just goes again.

This appears to be a drawing resource issue...nothing related to CPU or GPU usage by the video engine. This is something that has not been reported as a problem with VEGAS for several versions now. I will see if our team can reproduce this problem.

That would be awesome. Thank you

To help them, it would be useful for them to know your system specs... what CPU and GPU you use, amount of RAM, version and build of Windows, that way they have a starting point to go from when trying to reproduce your issue.

The specs are in the original post. It is the most recent version of windows 11 is the only thing I left out.

Gigabyte vision 3080ti

Corsair vengeance ram 64gb ddr5 running xmp 1 at 5800mhz

x670e prime pro wifi motherboard

7800x3d amd

none of this is overclocked at all

Could be a myriad of reasons.

Let's start off with outdated drivers and updates.

Start with updating your graphics card if you haven't, then move onto Windows updates,

Make sure optional updates are also installed as they might fix your issues.

-----------------------------------------------------------------------------------------------

Are you overclocking any components? Is your BIOS automatically set to default?

Newer motherboards on default can ramp up a processor by overclocking it on auto without you giving it consent, make sure you have limits on that processor set by AMD.

-----------------------------------------------------------------------------------------------

Try using Revo Uninstaller to completely remove Vegas and any registries left behind and then re-install it again it is a free software as well, only the program will be uninstalled (possibly presets as well if you have any so make sure you save them) with any registry that gets left behind during the uninstall procedure.

-----------------------------------------------------------------------------------------------

If it still continues, I usually love to blame Windows because this type of situation has happened to me but with other stuff like Windows Explorer :D

Thanks Microsoft.

I build pc's so I know all of this. I have been building and fixing pc's for nearly 20 years and the normal, check this, stuff has been done. I check for driver updates for all of my hardware constantly just in case something has been improved or fixed, especially GPU & chipset drivers, and this is genuinely the first time I've had this particular issue with Vegas. I never overclock because it is literally pointless if you have a high pc already. I prefer stability. I have uninstalled everything that is useless with Revo and uninstalling Vegas and reinstalling does nothing with this new version of Vegas. Thanks for trying to help though. Its nice that this community is willing to help people with there issues.
