[Windows] Paint bleeding when opening popups

[weisJ]

@weisJ I recorded a video so you can look at this problem https://mega.nz/file/PuAhBYjK#MGC-euIl_ty86a9DsmDzpQBCXz0pcc-dOOmi0p1Uiz4

@weisJ when will this problem be solved?

[weisJ]

@Ilolka1337 I have still yet to reproduce the issue. As I have already mentioned until then there is nothing I can do really. Have you already tried version 2.1.1?

[Ilolka1337]

@weisJ 2.2.1-SNAP | tests https://mega.nz/file/2vIixKKD#x4uhS7S8aQg1NTx7TGLNGUL_aoPOVlIRYC5VPa8I0OQ

[weisJ]

Are you building with the newest native binaries?

[Ilolka1337]

@weisJ I download from there https://github.com/weisJ/darklaf/actions/runs/121880047 I now have little disk space to store visual studio

[weisJ]

Don't worry you won't need visual studio. I was just making sure you are using the latest binaries.

Are you facing the same problems when opening the popup of a JMenuBar? Also could you try with the following line after installing the laf?

LafManager.install();
JPopupMenu.setDefaultLightWeightPopupEnabled(true);

What happens if you set your display scale to 100%?

[Ilolka1337]

@weisJ video https://mega.nz/file/z7pFGDZB#dvlONVPJnaeTiPiaBh2PvKnj9nFwBpBtKPTKTY8b7ws

[weisJ]

No need for the video. Could you please answer the remaining two questions?

[Ilolka1337]

@weisJ

Are you facing the same problems when opening the popup of a JMenuBar? Also could you try with the following line after installing the laf?

I did not notice a problem with this

What happens if you set your display scale to 100%?

also found no problems

[Ilolka1337]

@weisJ what was the problem really?

[weisJ]

It seems to be a combination of the heavy weight popup and the display scaling. Although it’s a bit strange that only the combobox popup is affected.

Could you check if using the system laf together with

JPopupMenu.setDefaultLightWeightPopupEnabled(false);

produce the issue?

[Ilolka1337]

@weisJ only works if I set true in this parameter

[Ilolka1337]

[Ilolka1337]

@weisJ if there are any other problems, I will write to you

[weisJ]

@weisJ only works if I set true in this parameter

What I want you to check is whether using the System LookAndFeel instead of darklaf produces the issue.

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
JPopupMenu.setDefaultLightWeightPopupEnabled(false);

Even though

JPopupMenu.setDefaultLightWeightPopupEnabled(true);

fixes the issue this isn't the way darklaf is intended to look. This way popups loose their shadow and the edges of the popup may be hard to spot.

[Ilolka1337]

@weisJ in new updates the same problems again

[Ilolka1337]

@weisJ only now it is not fixed using JPopupMenu

[weisJ]

@weisJ in new updates the same problems again

Does this mean the problem went away in some intermediate versions? If not I'll have to say that I never claimed this issue has been resolved and saying that the issue is still present doesn't add anything to the conversation.

@weisJ only now it is not fixed using JPopupMenu

This honestly reflects more what I am imagining would happen anyway. Good to know the issue is more consistent now.

Does

LafManager.install();
JPopupMenu.setDefaultLightWeightPopupEnabled(true);

still solve the issue?

[Ilolka1337]

@weisJ this problem was fixed in only one version; in new versions the problem appeared again only now it cannot be fixed with JPopupMenu.setDefaultLightWeightPopupEnabled (true);

[weisJ]

@weisJ this problem was fixed in only one version;

By fixed do you mean the issue wasn't present or it could be circumvented by using JPopupMenu.setDefaultLightWeightPopupEnabled (true);? Also which version?

in new versions the problem appeared again only now it cannot be fixed with JPopupMenu.setDefaultLightWeightPopupEnabled (true);

Could you provide sample code to reproduce the issue? Preferably for the popup menu case.

[Ilolka1337]

By fixed do you mean the issue wasn't present or it could be circumvented by using JPopupMenu.setDefaultLightWeightPopupEnabled (true);? Also which version?

it was fixed in one of the versions but I decided to install each new one so I don't remember the exact version now JPopupMenu.setDefaultLightWeightPopupEnabled (true); no longer works as a solution to the problem, I don't know what to do

[weisJ]

Well couldn’t you try out the last few versions and check whether it works? Knowing which version doesn’t have the problem would be a great benefit in solving it.

[Ilolka1337]

@weisJ in 2.4.2-SNAPSHOT JPopupMenu works again and without JPopupMenu the white background pops up again

[Ilolka1337]

@weisJ my program just crashes after I go to one of the tabs where JList is used

[Ilolka1337]

@weisJ Version: 2.4.3 SNAPSHOT

[weisJ]

Please create a separate issue with the necessary information.

[Ilolka1337]

@weisJ I began to notice that the problem is not only in ComboBoxes, when I am in the program menu for a long time, the same thing happens, I minimize and re-deploy the program and a large number of copies disappear. How can I help you reproduce this problem?

[weisJ]

You can do the following thing:

• Try out different monitors (if possible).
• Try out different screen resolutions.
• Try out different scaling factors.
• Try out different versions of Java (Preferably fresh installations)
  • Also try with -Dsun.java2d.dpiaware=false and -Dsun.java2d.dpiaware=false.

To get a grasp on this issue its necessary to know what parameters cause it.

[Ilolka1337]

@weisJ his problem is not displayed only in the usual laf UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); I also noticed in DarkLaf a very small Font, could you fix it a little later?
