[BUG] - r2modman has entire screen white after some time

[KarmyDev]

Describe the bug On Linux Mint 21.3 x86_64 r2modman's screen randomly becomes white and unusable. r2modman's version is 3.1.48

To Reproduce Steps to reproduce the behavior:

1. Run r2modman, select Lethal Company, create new modpack
2. Add some mods, launch modded
3. Keep launching modded, closing game, possibly minimizing the r2modman window
4. After doing step 3 over and over and maybe some time, r2modman should be white

Expected behavior r2modman showing list of mods /or/ popup about game being launched

Same issue, also with 3.1.49 (and 3.1.48), on Ubuntu 22.04.4.

edit: Running as root (and disabling some of AppImage's sandboxing!?) is not a suitable workaround.

Same. Win 11 Pro 23H2

3.1.49 works on Ubuntu 22.04.4, with a caveat.

Run it from a terminal with sudo ./r2modman-3.1.49.AppImage --no-sandbox.

Still happening with 3.1.49 on windows.

for me (windows) just having r2modman open on the lethal comp modding menu after some time (2-4 min) causes it to blank out. pretty annoying especially when browsing for mods / edit config of them

Been happening on Windows (10 & 11) for me for a few months now (since 3.1.47)

Same issue on Windows 11 23H2 22631.3880! No matter what happens, after several minutes, the window will turn blank.

It seems that this is written to stderr at the same time as the window goes blank:

White screen problems have progressed for me to the point just having it open for Lethal Company for 3-5 minutes will result in a white screen.

I've switched to Gale Mod Manager as a workaround. It's better than r2modman in many ways. Still thanks to r2modman for the effort and for being the pioneer and a viable FOSS alternative to Overwolf. ^w^

I somehow managed to fix this, when white screen happen I'm trying reupdate the existing profile over and over until the mod successfully installed.

Same issue, keeps happening very consistently after just having r2modman open for a while. My mod downloads stop after this white screen happens.

How long have u been using gale mod manager and is it harmless? Meaning is it not a virus?

[KarmyDev]

Downloaded latest version of r2modman (3.1.49) from Release tab, It appears that this issue reoccurs again. This time I just left r2modman on an update existing profile import screen which was downloading mods, as I returned to my pc I was greeted by white screen (I have no idea if downloading is paused by this)

Same issue

[xander3000]

Same issue here but only happens on my laptop, doesn't happen on my desktop.

Fixes when debug mode is running all the time. If an error occurs, the debugger catches it and you can continue working in the manager CTRL + SHIFT + I

[swiftswordrush]

While in the r2modman window, CTRL + SHIFT + I brings up the developer tools for the manager, as WinoMot's comment indicates (and the wiki for r2modman). So I waited for a white screen and pressed the buttons to see what would happen: to my surprise, the developer section pops in and says that the tools are disconnected and will be reconnected upon refresh.

Pressing CTRL + SHIFT + R refreshed the r2modman window and the white screen went away for me. I don't know what's causing the error, but this temp fix is good enough for me for now.
