I have already made a thread about this recent problem I'm having (started a few months ago, I haven't changed anything on my end) but since nobody could provide answers I decided to create a new topic explaining this glitch a bit better.
WHAT PROVOKES THIS DISGUSTING ANNOYING GLITCH:
1 - Performing the split clips action after a certain number of times.
2 - More frequently, right clicking on a cut section of the MP3 audio (to rename it for example) causing the options to blank out, the Master Volume Slider to turn blue or black in color and glitch lines begin to appear everywhere. The fade sections of the clips will appear black with numbers and letters in them, all out of place. The more actions you continue performing, the more limited you become, until you can't do anything besides Alt+F4. Attempting to save will present you a blank box with no options, attempting to click on the X (top-right) will do the same.
Up above you have a link to a video I made, showcasing this glitch. In that video you will see me cycling through 3 different projects, the longest one that I keep opening is the corrupted file. As you can see, in the other 2 projects I'm able to cut clips, adjust fade without anything moving (everything stays where it's supposed to).
I tried reinstalling Vegas and resetting everything as I said I would but this glitch keeps happening on this project (I had an earlier clean version saved on a USB that I copied onto this PC to give it another shot).
Once the project becomes entirely corrupted, you can no longer work on it in any way, everything is frozen no matter what you click.
In order to continue editing this project, I need to do it "gently": I perform one basic action such as cutting, I save. Another cut, I save. Rinse and repeat. If the next action makes weird lines appear, I don't save, I close without saving and reopen the last save. If you're suffering from this problem, you need to make sure you turn off autosave, as it might kick in at the wrong time, because believe me, if the project happens to be saved as those weird lines appear, everything is going to end up F*CKED.
Thank you for your interest, please only comment if you have helpful feedback. Once again, watch the video it shows the error report at the end. And no, it's not a nahimic driver issue or whatever.
