Unexpected "Unsaved Changes" often appear on opening

Describe the bug Using v21.1.2 on Windows 10 (also seen in earlier application versions), opening up a .drawio file results in an "Unsaved Changes" popup. However no changes have been made. It seems as if a .drawio.dtmp file gets left behind on exit, despite no unsaved changes existing.

To Reproduce There seems to be no obvious cause for this, it seems to happen roughly 50% of the time on opening a file. The file is saved to a local drive (that's backed up to Google Drive).

Expected behavior If no unsaved changes exist, the "Unsaved Changes" popup should not appear.

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version 21.1.2 (and earlier)

Desktop (please complete the following information):

• OS: Windows 10
• Browser Not applicable(?)
• Version Windows 10

Additional context Performing a diff between the .drawio and the .drawio.dtmp, only the first line has differences:

 .drawio:
<mxfile host="Electron" modified="2023-04-04T16:39:26.316Z" agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) draw.io/21.1.2 Chrome/106.0.5249.199 Electron/21.4.3 Safari/537.36" etag="lpaFChJrVhh1gKMAjnP1" version="21.1.2" type="device" pages="2">
.drawio.dtmp:
<mxfile host="Electron" modified="2023-04-04T16:39:30.416Z" agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) draw.io/21.1.2 Chrome/106.0.5249.199 Electron/21.4.3 Safari/537.36" etag="bkc0WToFAiR4kEjK_6jY" version="21.1.2" type="device" pages="2">

The two differences being:

• the modified attribute (which is different by a few seconds)
• the etag attribute.

I, too, experience this on a regular basis. I use the desktop app version on Windows 11, and every time I open a file it shows "Unsaved Changes" even though I definitely saved/exited previously.

Same experience. it is very weird. I am very confused and don't know whether to choose 'edit' or 'discard'.

[davidjgraph]

drawio desktop versions? Are you saving to a folder that is a synced cloud storage folder?

[wan-nie]

I'm using a desktop version. When I deleted the related 'drawio.bkp' file, the popup disappeared. It seems the 'drawio.dtmp' file also causes the popup. diff main.drawio '.$main.drawio.dtmp' shows the following.

[davidjgraph]

21.2.8 isn't the latest version, please use the latest desktop build.

[GregoryFrederick]

@davidjgraph - Yes, I'm saving to Google Drive. Is the asynchronous storage location the issue?

[davidjgraph]

What version of draw.io?

[GregoryFrederick]

@davidjgraph - 20.8.16. I haven't used it in a while. Should this be fixed in a more recent build?

[GregKGS]

Can't speak for @GregoryFrederick , but I've been upgrading drawio since raising this ticket and can confirm I am still seeing it on on v21.6.1.

Likewise, I'm saving to Google Drive.

I've just tried recreating the issue, here's what I've found:

If I open a file, edit it, save it and quickly exit (as fast as I can), the problem doesn't seem to happen 👍 If I open a file, edit it, save it and pause for 10 seconds before exiting, then the problem occurs. 👎

(I've only tried this a couple of times, so can't confirm this is 100% the case.)

Hope this helps!

[davidjgraph]

Thanks @GregKGS that's useful to have something precise to test.

I also experience this very frequently (nearly 100% after working on a diagram and reopening later). I save drawings to OneDrive. What is worse, it's often an older version of the diagram than the one I saved.

Haven't found out what triggers it. When I try to draw, save, close and reopening, it basically never happens. But when open draw.io to work on documents from yesterday, it nearly always does this.

The issue is still there in Windows desktop version 22.0.0. Either installer or no-installer will cause this problem.

Every time I need to delete bkp and dtmp files manually.

[GerMUC]

I confirm the same issue with v22.0.2 - using OneDrive.

Should be fixed in v22.1.16
