@acer 

Thanks for the tweak. I hope we will see this integrated one day.👍

Just an observation:

I have a Maple 2024 session running for more than a week with many worksheets open and no signs of icons dissapearing.

What I did yesterday: I configured (in the NVIDIA control pannel) my computer (Maple 2024 still running) such that Maple 2023 uses exclusively the NVIDIA graphics processor. Et voila

All this without any extended use of Maple 2023. Maple 2024 is not configured to use a particular processor and the system can chose the graphics processor. I cannot tell at the moment which resources the Maple 2024 session is using.

What is maybe more important: I started Maple 2023 in laptop mode (i.e. only the internal 2k display available). Now I am back in the office and have a 4k external monitor connected).

New: mouse over and minimizing do not bring all icons back

Concerning Java, there are IDE alternatives to Eclipse. By coincidence I talked to a software engineer who told me that his Java team recently switched to IntelliJ IDEA for a windows application. So there are options

@Carl Love 

I tried printlevel:=1000 and alternatively

trace(simplify);
simplify((x2 - x3)*x1 - x2*x4 + x3*x4 + (y1 - y4)*(y2 - y3));

From that I could not understand at which code line the simplification stopped. For other commands (like dsolve) I had more success with printlevel and trace. Can I do better here?

@vv 

I like this more than my current solution (that I did not wanted to share in advance)

eval(ineq*(-2),-2=c);# case c<0
                             b < a

To flip a < b to b < a for c<0

map(`*`, ineq, -c)*(-1);# case c<0
                             b < a

Thanks

@sursumCorda 

Simplify cannot be traced. Whatever simplify does I cannot imagine a reason why simplify should not perform a recursive operation on the remainder of subexpressions that were not simplified yet  as

simplify(- x2*x4 + x3*x4 )
                         -(x2 - x3) x4

This extra step is not a modification of existing simplifications, its just an addition.
For the time beeing collect has to be used

simplify((x2 - x3)*x1 - x2*x4 + x3*x4 + (y1 - y4)*(y2 - y3)):
collect(%,x4);
       (-x2 + x3) x4 + (x2 - x3) x1 + (y1 - y4) (y2 - y3)

Maple 2024 uses a JDK

different from Maple 2020

I looks to me that this change was required because future support was not guaranteed.

I think future Maple versions will still be Java based because I do not see an alternative for a multiplatform "WORA" application. Even Microsoft supports Java.

Let's hope for a better Java Virtual Machine and/or Microsoft OS interfaces.

@sija 

I did the manual export on a 4k monitor. This might be a reason for better quality.

I do not have 2018 installed,  so I cannot check if the quality changes.

I suggest that you send a separate question for ways to programatically export. 

@nm 

If I add up the displayed Memory of all active worksheets in my session and compare it to the GUI task (javaw.exe): The GUI task has allocated about 2 Gb which is roughly 1/3 of all added Memory entries. This fits to what you said (with quite some overhead).

I have made an "interesting" observation: Memory equals 4.18 M after a new worksheet has been created.

Entering a single character (without enter, i.e. nothing send to the mserver.exe task jet) changes Memory to 54.18 M. This further supports that Memory is GUI related.

I consider your reply to be a good working hypothesis. Thanks

Update: The overhead is probably the Java Virtual Machine required to run Java Code

Does not work for me (2024). What works

expr:=3/2*(y-1)^(2/3)-3/2*x^2-c__1 = 0;
limit(expr,[y = 3,x=-7]);

@sija 

With Maple 2024 I get an error before, because plotAll(t) does not exist in the the worksheet where I pasted you code. In which file shall I paste it?

With Maple 2024 I exported manually (right click).

Nice animations.

Suggetion: Saving the files in workbook format could make browsing easier.

@Scot Gould 

Ok, that's statistically significant enough for me to know that I'm not representing an exotic case.

If you want to check one day for installed graphic cards:

Open the device manager (right click on the start button) and expand the display adapters entry.

Looks like this on my machine

@Scot Gould 

What you said fits to the observation that the icons that disappear use system functions of the OS.

What I do not know for sure is the first occurrence of this phenomenon. For sure I observed it with 2022, 2023 and 2024. Not sure whether the old Java platform (until Maple 2020) had the issue.

Since it takes a while to manifest, I suspect some memory / cache dependencies. Maybe internal and external graphic cards play a role as well.

What would help to reduce the number of suspects would be a log function of Maple which logs session start, number of servers connected to the GUI and memory usage. I don't know if such a thing exists.

What would also help to better understand this issue: Are there configurations/users that do not experience this at all under Windows 10?

Maybe uninstalling Maple 2020, following Ronans advice of removing other java applications, could fix it.

If I may ask, are you running older versions of Maple and do you have an external graphics card (I have an NVIDIA and use Maple in 4k mode)?

This way, all solutions are incorrect

solve(torus1<0,{x,y,z});
eval({%},[x=3,y=2,z=0])

However, the questions which had no tags a few hours ago now show tags in a new browser session. (I had to restart my computer in the meatime.)
