QT won't work properly when compiled

[andi448]

Describe the issue

I'm trying to compile the newest release v4.2.0 (but had this issue since v4.0) and it compiles without errors, but I can't use it, because if it opens a windowed dialogue, I get a black window instead and can't click anymore.

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

1. git clone https://github.com/PIVX-Project/PIVX.git
2. git checkout v4.2.0
3. ./autogen.sh
4. /configure --with-incompatible-bdb
5. make
6. sudo make install

Expected behavior

The QT should work properly.

Actual behavior

If I click something and get a windowed dialogue, but it's black (see screenshot) and I can't click anywhere, nor can I exit the program via the "x"-button. I have to stop it via terminate command.

Screenshots.

This is what I get, if I want to unlock my wallet for staking:

The problem is persisting with v4.3.0.

Could possibly be the "upgrade wallet" pop-up showing off-screen?
Did you previously had two displays connected?
Have you tried bringing back off-screen windows (ALT+spacebar, ALT+F7 and move, etc...)

I don't think so, because if I'm starting the qt extracted of the released pivx-4.3.0-x86_64-linux-gnu.tar.gz, it just works fine.
No, I've just connected a monitor for initial installing the OS, after that I just login via xrdp without any monitor connected.
Tried the combinations, ALT+space opens a search bar and ALT+F7 doesn't seem to do anything.

I've also cleared the ~/.pivx folder and ~/.config/PIVX.
It seems that the buttons on the left side are also hidden until I click on one, so I think qt isn't compiled properly?

This also persists in v5.0.0.

This also persists in v5.0.1.

spun up a fresh debian 10 VM, followed the required packages instructions in doc/build-unix.md, configured with --with-incompatible-dbd, started the wallet (regtest mode, with -legacywallet initially, to ensure that a subsequent run would show the HD wallet upgrade notice). subsequent run showed the notice in both default and dark theme without issue.

Thanks for testing, you've led me to the idea that my desktop environment or language settings could be the problem, so I've also spun up a few virtual machines and came to the conclusion, that KDE somehow seems to cause the problem. If I use Gnome, it works fine (even without recompiling).

But now I don't know on whose side is the incompatibility? Is it qt to KDE? How can I determine that?

there hasn't been interaction here in an year long, can create another issue if needed, closing..
