Hi. Anyone having trouble with window focus after starting APP ? I am running Mint 19.3 with Mate desktop - fully updated. Quite often (very often actually) after I start APP the "click to focus" stops working and cannot get focus on terminal, browsers etc. Also cannot close windows or bring them to the foreground etc. Whole desktop screwed.

Fix 1. Login to console and kill -9 APP. seems to fix.

Fix  2. kill desktop and start again.

Fix 3. Go to panel and try to minimise then unminimise windows.

This happened also on previous APP versions. Currently running APP v. 1.082

As long as I stay in APP then everything fine until I want to bring up other terminals/windows. 

Some mismatch between graphic libraries I presume.

Anyone got a less intrusive fix ?

Thanks.

Nick

Interesting, my main machine is running the latest Linux Mint and I'm not having this issue. What steps do reproduce this for you? Just starting up and trying to select the main window?

Vincent - are you using Cinnamon desktop ? I am using Mate since Cinnamon used to

create other issues with other software. Maybe because the PC has been upgraded

many times and have some dodgy libraries lurking around. Just wondered if anyone else had similar issue. If not then some software  issue with my desktop, I have all sorts of stuff installed over the years which you wont have if you installed a fresh clean copy.

It seems to happen randomnly. Sometimes run APP and close it and no problem, other times desktop "stuck". Doesn't happen with any other software I use and is definitely

a problem when I use APP.

Yes Cinnamon. I've had good luck with it tbh, no issues with all kinds of software (which impressed me to the point I switched to Linux, after years not having used it). 🙂 I do keep a rather clean system and it is about year old now. So maybe an issue that got introduced at your site, but that's hard to say. Can you test on maybe a virtual machine running a fresh Linux Mint desktop? Just as an idea?

It is weird this only happens with APP though, do you have any other Java based software?

I have another PC with Mint 20, but it is a bit of a pain to use as it is headless and

in another location. 

Might give it a try at some stage and let you know if it has issues as well.
