Graphics issue

Hello again.

I am having trouble running games, because the display is not working for some reason, attached is a screenshot to show you what I mean.

This is specific to my new development desktop and only occurs for games created with Construct3, as everything else works just fine, e.g. other linux games, steam,whatever.

All of my graphics drivers are updated.

I don't know the answer but have some suggestions.

What browser do you use? I think best to try Chromium.

You may have already tried this, but have you tried different type of drivers, like open source and the vendor provided ones?

In the past, I used Manjaro with a Nvidia GPU, I remember one of the drivers would just give black screen with only DOM elements appearing (which didn't react, like it crashed) for C3 games, the other driver was better and a 3D C3 game looked correct (but I recall there being refresh rate issues, and I couldn't solve it, so went back to maining Windows).

Also, again I'm not super familiar, but could Wayland be the issue? I seem to see that pop up often in reddit for Linux gaming issues, although this may only be relevant for Nvidia or not relevant at all, just a guess!

In desperation, I cleared all the browser data, web storage, checked and re-checked the drivers, etc.

I even uninstalled and re-installed Construct3 several times.

But still the problem is NOT fixed.

I am really bummed out...

The expensive new power-house desktop I specifically purchased for all my game development activities, is useless for Construct3.

Strange how all other linux games, steam games, also those I created with Defold or plain vanilla work just fine.

Maybe I should not have renewed my subscription this year.

Maybe this helps (fingers crossed):

Do any error logs show up on the browser console when you start the preview?

I created the following ticket:

github.com/Scirra/Construct-bugs/issues/7742

For those out there who are still interested, I somehow managed to fix this problem.

Wondering if it might run on another browser, I fired up Firefox and noticed that the issue was not present in that browser.

I then switched back to Chrome, and magically it's working again!

This sounds pretty bizarre I know, but I thought I'd at least record it hear just in case.

Oh yeah, and a big thanks goes to Ashley, who took the time to review my bug report and respond with kind words.

You can always look into chrome://gpu/ and then test various settings here chrome://flags/
