The cut and paste is a little wonky

because you didn't read my link which explains how to format :( i'll edit your post

@dankcushions When I run the game with verbose logging, exit the game, and check the /dev/shm folder, I see no log file. Only mono.513 file.

this is not possible in a standard retropie install. you're not rebooting before looking at the folder, I hope?

What is the output of ls -l /dev/shm/ ?

No glitches when running those other games.

Meaning you probably can't run content at odd refresh rates for some reason, maybe something about your retroarch video synchronization settings ?

Drdave79

@dankcushions Nope. I launched the game with verbose logging. Played it for about a minute. Excited the game and checked the folder.

When I run that command, I get mono.520

dankcushions

@Drdave79 well, i refer you to my previous requests for all info and command line output

@dankcushions I now have a runcommand.log but it's empty.

runcommand.info:

/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbneo/fbneo_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg "/home/pi/RetroPie/roms/arcade/sf2.zip"

retroarch.cfg

video_refresh_rate = "60"
video_fullscreen = "true"
video_fullscreen_x = "1280"
video_fullscreen_y = "720"

Drdave79

@dankcushions I did use pastebin.com.

barbudreadmon

@Drdave79 again, you should make sure everything is fine with your synchronization settings, maybe you need

video_vsync = "true"
vrr_runloop_enable = "true"

?

Edit: also note that i just added a core option to force 60Hz, however you should only consider this as a last resort workaround since it'll make games run faster than they should...

in what sense? the last logs you have posted have just been pasted directly - you just did it again now!

i appreciate this hobby can get technical and isn't always intuitive, but to support people in the least amount of free time there's lots of documentation and specific instructions on how to seek support.

read this first says about logs:

Format your posts! - put small logs in code blocks - see http://commonmark.org/help/ - and put large logs on a pastebin type site like http://paste.ubuntu.com/ http://pastebin.com/ or similar.

there's 3 options there, all of which are better than just pasting logs/configs directly into the forum (although even that is better than not posting them at all..). please read carefully the read-this-first page next time you seek support, which appears to be quite frequently. there is better things we could all be doing than repeating what has been said at the top of every forum page.

i can see from this that you didn't run with verbose logging via the runcommand, although it should still generate the file regardless (and you still haven't run the command like i instructed). you should also paste all relevant configs, /opt/retropie/configs/arcade/retroarch.cfg, /opt/retropie/configs/all/retroarch.cfg (note: codeblocks, pastebin, etc etc)

but yeah, what's all these video settings? they're not stock.

I think that's what they meant by:

Are you referring to:

retroarch.cfg

video_refresh_rate = "60"
video_fullscreen = "true"
video_fullscreen_x = "1280"
video_fullscreen_y = "720"

...? This is their /dev/shm/retroarch.cfg, automatically generated here at runtime; mine is identical to this (I am using a 720p TV.)

...unless you mean the:

hdmi_group=1
hdmi_mode=4

...in their /boot/config.txt; those, indeed, are not stock.

Drdave79

@sleve_mcdichael Thank you Sleve for helping to clarify. I'm not trying to be difficult at all. I've always appreciate everyone's time here. But yes, I did run the command and report back as @dankcushions has requested. He must have missed my response.

@dankcushions I wasn't aware I had to run verbose logging via runcommand. But even you admit that it should still generate the file either way. I can definitely add the additional logs you requested from pastebin. I will do that shortly.

If my /boot/config.txt isn't stock, where can I obtain the correct file to avoid more problems?

Drdave79

@dankcushions I must not be using pastebin.com correctly. I paste the log into the top. I give it a name and click create new paste. Then I hit copy raw which places it in the clipboard. Then I paste it in this forum. I don't want to continue to frustrate you.

After you click "create new paste," copy the URL from the address bar and post that here, like: https://pastebin.com/DUj6i1Gi

We can click on that and view the paste in a new window.

@Drdave79 said in FBNEO Screen Glitches. Need advice please.:

Yeah you have to enable it each run, or you could enable it permanently in /opt/retropie/configs/all/retroarch.cfg with:

# Enable or disable verbosity level of frontend.
log_verbosity = true

If my /boot/config.txt isn't stock, where can I obtain the correct file to avoid more problems?

You can extract the file from the stock SD card image using 7zip on your PC.

I hope this works.

Drdave79

@sleve_mcdichael Thanks again Sleve!

Drdave79

@barbudreadmon Under which config file?

sleve_mcdichael

@Drdave79 said in FBNEO Screen Glitches. Need advice please.:

When I run that command, I get mono.520

I have no idea what this is; it doesn't exist on my system, and googling it only shows me ads for wigs.

(Edit: that was for mono.513; mono.520 shows ads for bikes and laser printers instead. It seems your filename is changing.)

Is it still there? If you're curious like me, you would see what kind of file it was with the file command, like:

file /dev/shm/mono.520

...and if it said something like "ASCII text," you might even inspect it with nano or less to see what its content was.

If it's not there, or you're not curious, just do a reboot, and then try again to generate the verbose log.

Does it improve any if you disable the overlay? They don't eat up too many resources*, but sometimes every cycle counts.

*(if you use shaders and overlays at the same time, it gets pretty heavy.)

Drdave79

@sleve_mcdichael Never really had an issue before with shaders and/or overlays. Tried removing the overlay and still saw the glitch a few times.

I did update to the latest lr-fbneo binary.

When comparing the standard config.txt and mine, I only noticed two differences. hdmi_mode=4 under one section. And an extra gpu_mem=256 under the [all] section. I've removed the last one and tried it again. Only saw one blurr in the 5 minutes of playing SF.

I'm not going to waste anymore of anyone's time on this. I'm just going to accept the random screen glitching. It's not horrible, just noticeable. I really appreciate everyone's help.
