A new version of BOINC is ready for public use. You can download it here. See the release notes and version history for details.

I instal it but Screensaver flash and change very fast between BONIC logo and logo of work.
So I uninstal v.7.2.39 and instal old version who I have 7.2.23

Same problem on my computer, after installing this latest version. As a result, I no longer use BOINC as my screensaver. (Windows 8)

@filchef:
Could you please state what operating system and brand and model videocard you use? Also on what project(s) you see this behaviour, and which science application(s) run at that time. Which drivers?

I use Windows 7 Ultimate
My videocard is embedded Intel(R) Q35 Express Chipset Family (Microsoft Corporation - WDDM 1.0)
Driver is 8.15.10.1749

Projects are FightAIDS@Home and Mapping Cancer Markers.

OK, I had a chat with the BOINC developers about this. There have been no changes in the behaviour or the code, or the libraries of the screen saver, between versions 7.1.17 and 7.2.39.

Flickering of the screen saver can point towards problems with the driver. Does it only do it with BOINC, or also other (OpenGL) screen savers? Have you tried to renew/reload your driver?

Both of the projects you run are done through World Community Grid, aren't they? Have WCG released a new screen saver/graphics application lately? What, if anything, do they say about it on their own forums?

I have the same problem.

Use Windows 7 Home edition
Pc are equipped with a AMD 6 with radeon HD graphics latest drivers.

And which projects?

Yes but when I use v.7.2.33 screen sever working fine with World Community Grid also regular Windows screen severs working fine with both versions

sorry..Seti@home

I'm sending all your material in to the developers. Is all I can do.

OK, a request from the developers. The people with the flickering problem on BOINC 7.2.39, please install 7.2.39 again if you went back to 7.2.33, and/or enable the BOINC screen saver.

When you see this flickering, stop the screen saver, navigate to your BOINC data directory. Now open BOINC Manager, take note of which applications are/were running. Look these up in the \BOINC\slots\ directories.

With each of these tasks there should be a stderrgfx.txt file. The developers would like the contents of this file. You can just post it here. his is the output log of the project screensaver, especially if there is an error. (Some project screen savers write to this log even when they run normally, but not all do.)

Some project screen savers may also write a stdoutgfx.txt file in the slot directory; this could also be of interest.

With thanks.

Edit to add system info:

Custom PC w/Intel MB and I7-2600k processor, no OC and 16GB RAM;
running Win 7 Home 64bit with latest updates;
NVidia GTX 660 2MB GPU with latest WHQL driver (332.21).


I have plenty of the desired file, all seem to contain the same info, so I chose the shortest.

My guess from looking at them all is that the screensaver is falsely detecting full screen request but then continuing to load and run.

stderrgfx,txt file contents from slot 6 follows:

Ok, no need for more of the stderrgfx.txt files. I have been able to reproduce the flicker on one of my systems. Am showing the developers a video now.

As best as I can tell, it is a problem with the BOINC screen saver, as my BOINC has no projects added and it's still flickering like a disco-ball.

Edit: It's a problem with just the BOINC screen saver, as it will do it as well when BOINC isn't running, but the screen saver is set to BOINC.

Sorry to mix this in with the screen-flickering posts. I noticed an issue with 7.2.39 and the add-on software BOINC LCS, which uses PHP to parse BOINC's client_state.xml file and presents it in HTML format.

It appears a new <language> element in the 7.2.39 client_state.xml file contains a character which prevents PHP code from parsing the XML file successfully. BOINC LCS works correctly once I remove the <language> element manually, but the element is automatically restored after some time. Changing the language value within the BOINC manager menu options does not resolve the issue either.

Is <language> a new element, is the stored value correct, and does this mean a fix to the BOINC LCS parsing code is needed (it currently calls the PHP function simplexml_load_file)?

Thank you

This issue was fixed last night and will appear in the next version. The developers are going for a hotfix, due tomorrow. The screen saver problem is a tricky one and may take longer.

---

The hotfix has been postponed until after the HTC release has been done. I was asked what a hotfix looks like, the answer to that is that it'll just be a new BOINC version that you can install over the previous installation.

When it's available you'll get notification through BOINC, or we'll tell you about it through this forum.

The screen saver problem is a troubling one. I've made a ticket for it at the bug-database, [trac]#1338[/trac].

I installed 7.x.39, and it is very unstable. The Windows keep jumping between what I think is the screensaver and the normal window.
I uninstalled 39, but the screen went blank, Windows Explorer gone away. I keyed in Alt/Ctrl/Del and got the task manager, and restarted Windows Explorer (WinXP).
Also the uninstall of 39 via control panel did not refresh the application list. This may be part of the Windows Explorer vanishing.

I re-installed 7.x.33 my previous version and all is well again .

I have installed the new version of BOINC 7.2.39 and now cannot get any projects at all, please help.
I am running BOINC on Windows 7 Professional 64-bit.
Project I was running before upgrade was SETI

Barney.

now cannot get any projects at all

And by projects you mean what? Tasks (the data you crunch) or did you want to add Einstein, Milkyway, GPUGrid, World Community Grid, Primegrid, or any of the other projects?

If you really meant tasks, please post the part of your event log (CTRL+SHIFT+E) from what BOINC says when it asks for work from Seti@Home.

You didn't set BOINC to No new tasks? Check that by going into BOINC Manager, Advanced view, Projects tab, select Seti@Home, on the left in the menu you must have a button called "No new tasks". If it's called "Allow new tasks", click it. The button shows the option you have, not the state that it is in. Same goes for the Suspend/Resume buttons.
