Description

Please see the attached video.

Bug 1 (at 00′12″ in the video): All main menu items except "muCommander" are missing. When changing from the Downloads directory in the left pane to the root directory in the right pane, the missing menu items appear.

Bug 2 (at 00′41″ in the video): When switching to "Custom folder", the appearance changes undesirably from FlatLaf to CDE/Motiv. FlatLaf is unavailable.

(@Andreas0602 - that video is in terrible format, I'm having a problem watching it both in Firefox and VLC - it looks like nothing happens until you scroll and only then the video content gets updated)

[Andreas0602]

It's a mp4 file encoded with H.264 ... should be quite a common format. Anyway, I've just converted it to webm VP8 with a reduced resolution of 1920 x 1080. How about that one?

H.264 but something wasn't good in it. This one works great.

@Andreas0602 ad Bug 2 - do you reproduce that always? Is it only for Downloads or for other folders you have the same problem?

[Andreas0602]

I reproduce bug 2 always. And it happens for all folders. Therefore, I've just changed the title of this issue to "Erratic behavior".

[pskowronek]

I cannot produce bug 2. Could you change log level to finest and provide logs? Maybe this will give us some hint.

[pskowronek]

ad bug 1 - do you reproduce that always or randomly?

[Andreas0602]

Bug 1 occurs randomly.

Here is the log file from bug 2 with finest level: removed

ad bug 1 - I'm able to reproduce using debugger

ad bug 2 - I don't see anything obvious (you may remove the recent log above now as it contains some internal IPs and names). I set the same L&F and still nothing. However, I see this in your logs:

2024-05-08 22:53:32.270 [WT-EventQueue-0] DEBUG com.mucommander.ui.theme.ThemeReader:934 - Unexpected start of element executable, ignoring.

2024-05-08 22:53:32.270 [WT-EventQueue-0] DEBUG com.mucommander.ui.theme.ThemeReader:158 - Ignoring element: group1

I don't see anything similar in my logs. So, I have a hunch that it might be somehow related to Custom theme you have there. Can you open theme by Edit (you may first export it and provide it here):

This tells me, that probably changing anything in preferences might trigger defaulting to CDE/Motif - have you checked that?

Good.

you may remove the recent log above now

Thanks for the hint. Done.

Can you open theme by Edit

Yes, I can.

you may first export it and provide it here

Here it is: exported_theme.zip

Update on bug 2: The bug occurs whenever changing any preference (e.g. Time: 24-hour format -> 12-hour format) and then clicking the Apply button. So, your guess was right.

[pskowronek]

After importing your theme I can reproduce the behavior:

But only once and no more :)

ad bug 1 - the problem is caused by menu items being constructed in the background for a faster muC launch. The JFrame was not "revalidated" after updating the menu items. Fix on the way.

ad bug 2 - the problem was kinda race condition caused by loading additional L&Fs in the background (deferred loading) for a faster muC launch. When Preferences were opened and L&Fs loading finished just after that, the L&Fs dropdown was in unstable condition. The bug has nothing to do with custom theme etc. Fix on the way.
