glxinfo

Age of Wonders 3 v1.802 Linux version via STEAM.

Some strange vertical lines can be observed on the Main Menu but otherwise the game appears to work correctly in all other areas (i.e battles, global map)

It should obviously look more like this:

Ubuntu 18.04 LTS, using oibaf's ppa for the latest Mesa packages.

A search highlighted this previous bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=106531

Running this in a terminal:
MESA_GL_VERSION_OVERRIDE=3.1COMPAT steam steam://226840

Or changing the game's launch options with didn't have any effect:
MESA_GL_VERSION_OVERRIDE=3.1COMPAT %command% 

I've captured an apitrace of the issue but it's a bit screwy when replaying it - what I see occurs offscreen:

The playback window can be moved up beyond the limit of the screen by left clicking on the top left edge and choosing "Move"
Works best if you do that once the Main Menu is loaded.

I must've exported MESA_GL_VERSION_OVERRIDE=3.1COMPAT then done a glxinfo in the same terminal window.

Comment 4 andrew.m.mcmahon 2019-03-08 20:08:52 UTC

The mesa packages provided by oibaf's ppa were updated to use LLVM 8 so I've made another trace:
https://drive.google.com/open?id=1wPvrwTBTSYG7f3AQh-oolAYeXYn81ZnB

The issue is still reproducible. Again, replaying the trace has the same quirky behaviour as before.

Moving to Mesa core as this happens on i965 also.

I was sure this was a regression but could only run the game as far back as the 17.3 branch point on i965 and it was still present there.
