Display Corruption
I have a problem with the MD display corrupting. Unfortunately I haven't worked out what the trigger is, or even if it's consistent. It will be working fine, but at some point the display will start overwriting bits of the screen with copies of other bits of the screen. I've attached a short video which hopefully demonstrates the effect. Throughout this video I am just moving the mouse, not clicking (except when I change to Transaction Filter or whatever). Once it starts, this is happening across the whole application, not just the Graphs & Reports window - I just used the Graphs window as a reasonably 'clean' demo. No other application does this.
I've been using MD for a couple of years now, and this problem has existed throughout. I just assumed that at some point an update would magically fix it :-). That said, it's annoying rather than disastrous as restarting MD fixes it for a while - I just have to remember Ctrl-Q to quit, as the menus are corrupted!
Current MD version: 2024.2 (5172). Windows 11 Home, 10.0.22631 Build 22631. But bear in mind this has been happening with earlier versions of both MD and Windows.
Thanks for any help.

Grab help/console. Upload that here.

Uploaded. This is since I've restarted and the issue hasn't yet re-manifested itself. If you need the console after the issue appears, let me know.

just a user,
Is this the same PC used through windows 10 11 and multiple MD builds?
Possible keyboard mouse issue.

@Stuart: all extensions are up to date. I'm clicking around various screens to try and get it to go wrong again, but it's not co-operating at the moment!
@mhoggie It's not the same PC in fact - interesting idea though. Come to think of it, I've changed both the keyboard and the mouse within the last year, so it's been happening both before and after all of those things! I should smention that this is the only app affected - although in fairness it's probably the only Java app I use.

Naturally after raising the problem and unsuccessfully trying for weeks to deliberately get it to recur, I eventually stop thinking about it and *then* it happens again! :-(
I've attached a new Console file. Any thoughts would be appreciated.

Where is this "F" Drive physically located?

It's a second SSD inside the PC (SATA connected)

I notice that you have an Nvidia card with custom drivers listed on the C; drive. As with most Windows issues, have you tried updating those drivers? It really sounds like corrupted video memory which could be drivers or the video card memory itself.
Have you changed video cards since this problem occurred?

Hi @sth, I generally keep the video drivers updated - and they're up to date at the moment (and so must have been up to date when this recurred yesterday). I'm not sure what you mean by 'custom' drivers? I just run the update from the NVidia app.
I haven't changed the video card, but I have changed the PC :-). This did also happen on the previous PC, although I think that was NVidia too
As far as the corrupted video memory goes, this is the only application on which I've seen a problem - would I not see issues on other applications if the video memory was faulty? [reading that back it sounds sarcastic, but it's a genuine question - I've got no idea!!]

By custom drivers, I mean those specifically from Nvidia instead of default installed with Windows itself.
You might only see it with MD since memory issues can be very very tricky. Sometimes memory problems only happen when nearby memory is accessed. Sometimes it depends on the bit pattern. Sometimes it depends on the timing. Memory tests need to be exhaustive and not just reading and writing serial bytes.
The fact that you changed the PC but this is the same video card in all cases may point to a hardware issue. Of course can't be sure but the low level kind of overwriting graphics on the screen points to a fairly low level issue and shouldn't be part of the programming in Java or other high level languages.
I haven't seen this kind of display corruption but I am a Mac user.

Ok, thanks. Just to be completely clear, the previous PC had a physically different video card (I didn't do any swapping around of components, just bought a new PC!), but I think that card was also an NVidia model so it would presumably have the drivers in common.
Do you know of any good video card testing tools (for Windows of course - probably not, if you're a Mac user I guess :-))?
