SumatraPDF v3.6 bug?

[stealth30]

I just installed SumatraPDF 3.6 x64 and whenever I open a PDF for a brief moment before opening the PDF it will show the SumatraPDF About info (square with all the links to website, manual, forums, etc). Is there a way to get rid of that and just open the PDF directly? This was not happening with the previous version. Thanks

I exhibit the exact same behavior... and I also find it unpleasant.

Very distracting, I returned to the older version.

It happens with very small files too.

Yes, it's quite annoying, and it happens with any document, not just PDF's (Epub, etc). I downgraded to previous version until this is fixed

@stealth30 was closed in latest pre-release https://www.sumatrapdfreader.org/prerelease

basically uses the old "loading" message

The latest pre-release 64bit installer is broken, does not install anything

@kjk Questions/Ideas: 1. From a technical point of view, is it necessary to open the start screen when only a document is opened by double-clicking? or 2. Can the start screen be opened invisibly?

Please open an issue to track this

Done: issue

Hi to all , The very latest version 3.6 refuse to install on win 7 64 , it's like you compile the source for win 10 because when i applied the VxKex option to your program it work fine , so please recompile your program for normal win 7 users .

Thank you very much

I don't have win 7 for testing.

What exactly is the issue, what is VxKex option?

[GitHubRulesOK]

@kjk see https://github.com/i486/VxKex it is an API
on windows 7 apart from many problems like no decent Edge support the update installer barfs

---------------------------
sumA3C.tmp.exe - Entry Point Not Found
---------------------------
The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll. 
---------------------------
OK   
---------------------------

the official 32bit should run as SumatraPDF-3.6-install.exe and seems to work correctly as expected and ?ELEVATED on 32bit Have not got 7x64 active as majority are now Windows 10 apart from 32bit XP or7

ALSO for information a clean download of SumatraPDF-prerel-32-install.exe (unseen in browser) will NOT install cleanly 3.7.17674 it reports the above error

[kjk]

@GitHubRulesOK could you try 17677?

3.6 is build with vs 2022.

Is portable version working?

[stealth30]

After testing 3.6 and all 3.7 pre releases I reverted back to 3.5.2, the only version that works fine. 3.6 onwards all have the annoying delay when opening documents displaying the About info.

@stealth30 Please try 17831 pre-release and let me know if the flash issue is better for you.

You can either upgrade from within (Ctrl + k, Check for updates) or download from:

https://www.sumatrapdfreader.org/dl/prerel/17831/SumatraPDF-prerel-64.exe
https://www.sumatrapdfreader.org/dl/prerel/17831/SumatraPDF-prerel-64-install.exe

Hi Krzysztof, I tried 17831 pre release (released 3/27/26) and same issue, had to revert back to 3.5.2. Whenever opening any document (PDF, Epub, etc), before opening/displaying the document there is a brief moment (1 to 3 seconds depending on the document) that a screen shows like a folder location for a file). With version 3.5.2 the documents open perfectly, zero delay and no image displayed before the actual document.

Good description: "is a brief moment that a screen shows like a folder location for a file"

@kjk : We should reopen issues/5385

[rmmbr]

@kjk : I was able to take screenshots of the situation, which was also described by @stealth30 , and I noted it in the issue/5385.

[kjk]

Not sure I can improve it further.

It's a trade-off.

Before 3.6 loading was on main thread so the UI would just block when loading files. For files that take a long time to load, the app would completely freeze, which is not good.

So I added loading in a background thread which means no blocking / freezing but now it can show the temporary state when the file is loaded but the page is not yet rendered.

I can completely understand the decision. Thank you for your time and consideration of our question ... and thank you for your great commitment to Sumatra.

Last idea: suppress ShowLoadingNotif(win, path) when starting ...
... even if it's bad coding style ...

[stealth30]

What a pity, I've used Sumatra as default for opening PDF's instead of Acrobat for years as it was always lighter and cleaner. I will then have to stay with 3.5.2 because the reported issue is important, it really slows down the process. Thanks for your reply and for Sumatra

@stealth30 @rmmbr please try 17872

[rmmbr]

Thank you for trying again. I tested SumatraPDF-prerel-64-3-7-17878-install.exe.

It works perfectly for my use cases and my ThinkPad E580. I completely understand the advantage, or rather the necessity, of moving document loading to a background task. I now find it perfect ...
